Environmental Contaminants and Endocrine Disruption

Sara

This system governs sleep patterns, insulin production, blood pressure, and the ability to reproduce. The glands in the endocrine system produce hormones such as estrogen, insulin, testosterone, the thyroid hormone, and at least 50 others. The hormones travel to cell receptors throughout the body, triggering specific biological actions. The endocrine system is highly sensitive, meaning it can produce the right response even with extremely low concentrations of hormones. The effects of endocrine disrupting chemicals (EDCs) on the human body EDCs are chemicals which interfere with the normal working of hormones and the endocrine system in general. They can mimic certain hormones, affect their production, block them, prevent their movement through the body, or affect how they are metabolized. EDCs get into the body when we breathe in contaminated air, drink contaminated water, eat food with traces of EDCs, or if our skin comes into direct contact with them. Because EDCs prevent hormones from working normally, they can cause serious health complication to any body parts or functions that are serviced by the endocrine system.

Environmental Air Quality

Clean air is required to maintain human health and air pollution is a big environmental issue. The air we breathe impacts our well-being and is critical to supporting the amenity of everyone. While Australia’s air quality is generally very good, there are ongoing challenges. Some pollutants such as particulate matter and ozone still exceed national ambient air quality standards in built up areas, and concerns over industrial emissions still affect many communities. Environmental consultants play a vital role in maintaining air quality and addressing the impacts of air pollution on human health. One way environmental scientists help monitor air quality is by assessing the performance of businesses in achieving environmental approvals, and managing their ongoing operations and compliance with regulations designed to keep the community safe from air pollutants. Atmospheric scientists with experience in air quality consulting, odour measurement, dust and odour impact assessments understand the key air quality issues faced by businesses and how best to provide solutions that meet the expectations of environmental regulators and the community.

In the beginning

Sara

No blog on Environmental Scientists would be complete without a little acknowledgement of the woman who was at the very beginning of environmental science, in fact the whole environmental movement itself really was brought to light form her work; Rachel Carson. I know that I for one am grateful for what she uncovered and shared with the public through her book Silent Spring. That began our understanding of the devastating effects of DDT and the harm we as humans can inadvertently do to the environment and each other through the use of chemicals that were meant to make our lives better.. I think that creed that you hear from the medical profession “First do no harm” might well be employed in the chemical industries. I think the world would be a different place if were enlightened enough to take that That began our understanding of the devastating effects of DDT and the harm we as humans can inadvertently do to the environment and each other through the use of chemicals that were meant to make our lives better.

Enviro Scientists Down Under

Sara

I’ve been over in Australia recently and met a few enviro scientists in my travels. One of them was Steven Molino he works at Molino Stewart These guys cover an interesting range of environmental work. Working in NSW around Sydney they provide environmental consulting services for getting your land ready for development whether just for your esa or for land remediation for soil contamination and the like. They also specialise in natural hazard management; that is working on a large scale to help in situations that are what they term bushfire (wildfire) prone or flood prone to help minimise the risk and also manage it in the event of these emergency situations.. This is clearly something that is going to be needed more as we get an increase in the quantity and intensity of severe weather events due to global warming.

Ecological assessments differ from environmental assessments in that it focuses more on living things that is flora (plants) and fauna (animals) rather than more inert things like chemicals in soil, air and water
