The Impact of Plastics on Our Health & The Environment
Plastics have become an integral part of our daily lives, but their effects on our health and the environment are becoming more and more apparent. In this post, we’ll delve into some of the issues posed by the widespread use of plastic, on human health and on our planet.
We’ll explore topics such as microplastics, plastic pollution, and the chemicals found in plastics that can disrupt our endocrine system.
The Effects of Microplastics
Microplastics are small plastic particles that are less than 5 millimetres in size.
These particles can come from a wide range of sources, including cosmetics, clothing, and industrial processes.
Dr. Janice Brahney, an assistant professor at Utah State University, explains that, “Once they enter the environment, they can cause a range of problems.”
Research from the University of Plymouth has revealed that a single polyester garment can shed up to 1,900 microfibers in one wash, and these microplastics can enter the food chain when they are ingested by small marine creatures, eventually making their way into the seafood we eat. Microplastics can also cause physical harm to marine life, disrupting their digestive and reproductive systems.
There is growing concern about the impact of microplastics on our health.
Recent research suggests that these tiny particles can enter our bodies through the air we breathe, the food we eat and even the water we drink.
A study published in Environmental Science & Technology in 2020 found that people could be ingesting an average of 5 grams of plastic every week, which is the equivalent to the weight of a credit card. This means that we are consuming microplastics in our food and water, and these particles could potentially cause long-term health problems.
Plastic Pollution in Our Environment
Plastic pollution is one of the biggest environmental challenges we face today.
Dr. Jenna Jambeck, an associate professor of environmental engineering at the University of Georgia, states that, “Over 8.3 billion metric tons of plastic have been produced since the 1950s, and the majority of that plastic is still in the environment.”
Plastic pollution not only affects the aesthetics of our planet, but it can also have a serious impact on ecosystems. Birds and other wildlife can become entangled in plastic, or ingest it, causing injury or death. Some sea birds are mistakenly fed plastics as babies, resulting in them being too heavy to fly, so they drown when they head out to sea.
The impact of plastic pollution on our oceans is particularly concerning.
According to a report by the Ellen MacArthur Foundation, there could be more plastic than fish in the ocean by 2050 if current trends continue.
Plastic pollution can also have a direct impact on human health. In areas where plastic waste is burned, it can release toxic fumes that are harmful to human health.
The Impact of Plastics on Human Health
Many plastics contain harmful chemicals, including phthalates, bisphenol A (BPA), and other endocrine disrupting chemicals.
Dr. Leonardo Trasande, a professor of environmental medicine and paediatrics at NYU Grossman School of Medicine, explains, “These chemicals can disrupt the endocrine system, which regulates hormones that play a critical role in human health.”
Phthalates are often added to plastics to make them more flexible, but they have been linked to a range of health problems, including hormonal imbalances and reproductive issues.
BPA is a chemical used in plastics that can mimic oestrogen in the body and has been linked to obesity, diabetes, and other health problems. In many situations, this has been replaced by bisphenol S (BPS) which isn’t any better!
Endocrine disrupting chemicals can also impact foetal development and may lead to long-term health problems.
One of the most concerning aspects of plastic and health is the potential impact on unborn babies.
Research has suggested that exposure to certain endocrine disrupting chemicals during foetal development could lead to a range of health problems later in life.
A study published in the journal Environmental Health Perspectives found that women with higher levels of phthalates in their blood during pregnancy were more likely to have children with language delays.
Another study found that BPA exposure during pregnancy could increase the risk of behavioural problems in young girls.
It’s not just unborn babies who are at risk from the chemicals found in plastics.
Adults can also be affected.
For example, a study published in the Journal of Clinical Endocrinology and Metabolism found that men who consumed food from plastic containers had lower levels of testosterone than men who did not.
Summing it all up –
Plastics have become ubiquitous in our society, but their impact on our health and the environment is becoming increasingly concerning.
Microplastics are found in our food, water, and air, and plastic pollution is one of the biggest environmental challenges we face.
Chemicals found in plastics can disrupt the endocrine system, leading to a range of health problems, including reproductive issues, obesity, and diabetes.
It’s important to reduce our use of plastics wherever possible and to recycle and dispose of them properly.
By doing so, we can help to protect our planet and our health.

Applying a little foresight and forward planning can help to prevent renovation health hazards. Through the past decade, I have found that many of my clients have experienced health issues due to factors in their homes, I call these hidden hazards.
In order to equip you with information and strategies while renovating your home, I am going to share with you 5 of the common hazards… and give you strategies on how you can tackle them safely and effectively.
Mould
I’d say mould is a “complex beast.” Here are some key points in a nutshell:
Ultimately, mould is a moisture issue. If there’s mould, there has been moisture. Conversely, if something is wet for long enough (48 hours) you can have mould.
There are over 100,000 different types of mould, it comes in many colours and has many different moisture requirements.
It’s a myth that mould only grows in cold, dark places. Mould spores are present everywhere and can become active when there is enough moisture present.
Mould can be actively growing, yet be invisible and/or have no odour.
It’s also a myth that only mould that is black can cause problems to health.
Not everyone reacts the same way to mould. People can be allergic to it, or become sensitised over time. Others may have an immune system that can deal with it without them even realising it!
Mould can grow in all sorts of places – even in areas that you can’t see.
The biggest factor when it comes to renovation health risks is that any time you disturb mould, it releases spores. This means any changes to moisture levels, light, temperature, air movement, as well as physically disturbing it, can result in mould releasing spores.
Keep your eyes peeled for any signs of water, mould or damage: wood with “wood rot” (a.k.a. “water damage”), a “high tide mark” in the subfloor and on the stumps, brown stains (typically on ceilings and walls), paintwork that is peeling, cracked or bubbling, and swollen wood (door jambs, cabinetry, kickboards).
If you spot any of these, get in touch so I can advise on how to best manage the situation.
Asbestos
Asbestos is a material that most of us have heard of. I am sure you also know of the health risks, like mesothelioma that can result from asbestos exposure.
However, it is important to know that asbestos does not pose any health risk if it isn’t damaged or disturbed. Which means, you can live in a 1950s home and have no asbestos-related issues if you don’t make holes in the walls or renovate. This is great news – except if you do want to renovate.
Here are some facts about asbestos.
It’s strong, heat resistant and durable
It was used in a vast range of materials for many decades,
The peak usage of asbestos was 1950s-1970s,
Asbestos was banned in 2003, and
It is impossible to know if a material contains asbestos simply by looking at it.
Apart from “Hardie Boards”, cement-lined asbestos pipes and roof tiles, asbestos was used in electrical cable casing (this is the braided one), window sashes on hung windows, slagging, old laundry tubs, carpet underlays, tiles, bakelite materials and so many other materials.
If your home was built before 2003 and you are planning on a renovation, engage a licensed asbestos inspector to conduct a “demolition survey.”
Lead
Lead has also been widely used in a number of products, and was only phased out from use in paint as recently as 2010. Whilst leaded paint, like asbestos, when it isn’t disturbed poses little risk – if it is sanded or peeling, it can be particularly hazardous to health.
There are often no symptoms of lead poisoning for some years – and common long term effects of lead poisoning include loss of libido, reduced sperm count, lowered IQ, Alzheimer’s Disease, hearing loss, joint pain, stroke, and has been linked to many “diseases of ageing.”
Lead can be present in our homes in paint, solder, flashing (which can get into tank water), lead dust (from busy roads and industry) which can get into the soil or roof space, and even lead lighting.
What is important to know with lead is that the “spot tests” that you can get at hardware stores are extremely unreliable. It is for this reason that they are not something that I recommend. Instead, you can get samples analysed by an accredited laboratory.
If you suspect lead might be present then take extra care:
wear a respirator,
gloves and coveralls,
avoid dry sanding,
avoid removing paint with heat guns,
manage the dust to prevent secondary contamination, and of course,
keep pets, pregnant women, young children and the elderly away from areas being renovated.

Dust
Dust is certainly something you can certainly expect in any renovation.
But is dust safe?
I always err on the side of caution, and I would say, “no.” Better safe than sorry, right?
Two places where dust pose the biggest risks are carpets and the roof space.
Any time you are doing anything involving the ceiling or roof space be sure to have the dust removed prior. This could be installing insulation to cutting out a piece to installing downlights, and so on.
For carpets, I recommend that you spray them down with water, cut them into strips, roll each strip, wrap in a tarp and take it out to the skip. This will prevent dust becoming airborne as well as reduce the risk of spreading it through other parts of your home.
And of course, personal protective equipment is always recommended!
Plan Ahead and Avoid Renovation Health Hazards
Whilst we know how easy it is to get swept up in the vision and planning… However, you are now armed with important information to protect yourself and your family from the most common renovation health hazards.

Lead Levels and Lead Poisoning Prevention come to mind every October…
Because #ILPPWA: International Lead Poisoning Prevention Week of Action happens every year in the final week of October.
And 2021 marks the ninth week – thanks to the work of Elizabeth O’Brien, from The LEAD Group.
This year we have a lot to celebrate!
And what better way than to team up with the go-to person for all things lead, Elizabeth O’Brien herself.
Elizabeth has campaigned tirelessly for 30 years.
She is the co-founder of The LEAD Group, which was formed by a trio of parents of lead poisoned children.
This not-for-profit organisation has dedicated itself to preventing lead poisoning and spreading awareness about the risks.
As well, they have created almost 100 fact sheets and an array of solutions sheets which are freely available to help consumers arm themselves.
Which is unfortunately due to the shortfall of policy and guidance from federal government.
Today, we discuss some incredible progress that has been made –
Real wins for health (and the environment).
As well, we discuss WHY you should care about lead…
Because it isn’t only about lowered IQ…
And, of course, some action that you can take.
Important Points to Consider
Despite lead now being phased out of petrol, lead dust can still be found around busy roads, in soil and in ceiling dust
As discussed, from 1st October 2021 no Australian manufacturer is allowed to add lead to paint (apart from the two exceptions of anti-fouling paints and anti-corrosion primers), paint containing low levels of lead may still be used as tradies and suppliers use up existing stock
The best place to start is always with a Blood Lead Level test (for every member of the household) – if the result is not below 1ug/dL, then lead-remediation action needs to be taken
This is where the occupants of a building are sick because of something in a building where they spend time.
What makes people sick are known as “environmental stressors” – environmental hazards that place a stress on our immune system.
This can be anything from water damage and mould, to indoor air quality, to electromagnetic fields. It may be from components of the building itself, such as lead. Or even from the land where the building was erected – a form of “geopathic stress.”
In Australia, this term is somewhat understood, but far less people really understand what “Building Biology” is.
An Interview
When I began this career, I was an active committee member of my professional association. In my time as President, Nicole Groch from LivingSafe.com.au interviewed me about “building biology.”
Here is a snippet of it:
You may have heard of someone using a Building Biologist to check out their home for radiation, mold and sick building syndrome, but you really are not exactly sure what it is they do and who they are….
I personally have hired a Building Biologist to come out and measure the EMF from the Smart Meter in our home and I am very glad I did. It wasn’t just the smart meter that was the problem. It was also our transformer base study lamps, that we were using as bedside lamps and high EMF hot spot was found in our bedroom from an unearthed water pipe running under the floor. Thanks to the Building Biologist we were able to correct these hazards.
So what is a Building Biologist?
In a nutshell, a Building Biologist is a person who has been trained to assess the potential health hazards of a building or built environment. We adopt the Precautionary Principle, that is, if something hasn’t been proven to be safe, then we err on the side of caution and aim to minimise exposure or risks.
