Environmental Hygiene: Simple Measures You Can Take To Combat Environmental Pollution

We are living in a world where environmental pollution has become part of life. Civilized humans today must live in cramped urban areas, drink contaminated water, take in polluted air, eat contaminated foods, and endure loud, disturbing noises. What can we do?

As you read this, a strange object that looks like a 2,000-foot floating pool noodle is drifting slowly through the central north Pacific Ocean. This object is designed to solve an enormous environmental problem. But in so doing, it brings attention to a number of others.

Bad news for bacon lovers and barbecue afficionados. The World Health Organisation now deems bacon, sausage – and other processed meats – a serious cancer risk

The World Health Organization recently published its latest noise pollution guidelines for Europe. The guidelines recommend outdoor noise levels that should not be exceeded for aircraft, road and rail noise and two new sources: wind turbine and leisure noise.

Despite overall lower levels of harmful emissions from power plants and vehicles throughout the year, winter air pollution in the Eastern United States remains high. A new study explains why.

Carbon monoxide (CO), like many gases, cannot be detected by our human senses. We cannot see it, smell it or taste it. But unlike many gases, small amounts are extremely harmful to us.

Night has always been a difficult realm for humans: we’ve had to learn to cope with the cold and the dark to thrive in it. Since the industrial revolution we’ve found ways to adapt our homes and cities to operate during the night. But as our conquest of the dark continues, the border between night and day is becoming increasingly blurry.

The credibility of scientific findings hinges on their reproducibility. As a scientist, it is therefore disastrous when you are unable to replicate your own findings. Our laboratory has found itself in just this situation several times; in each instance, unintended environmental exposure distorted our data. Our first accidental foray into toxicology 20 years ago convinced us of the need to understand the reproductive effects of environmental chemical contaminants. The latest twist in our journey down that road adds a new dimension to an old concern, BPA.

Not everyone will readily admit to peeing in swimming pools, but it does happen. An anonymous survey from 2012 found that 19 percent of adults admitted they had peed in a pool at least once. But when you use a pool as a giant toilet, that yellow trail contains some nasty bacteria and parasites.

One of the main problems with plastics is that although we may only need them fleetingly – seconds in the case of microbeads in personal care products, or minutes as in plastic grocery bags – they stick around for hundreds of years. Unfortunately, much of this plastic ends up as environmental pollution.

In the first of many pending lawsuits to go to trial, a jury in San Francisco concluded on Aug. 10 that the plaintiff had developed cancer from exposure to Roundup, Monsanto’s widely used herbicide, and ordered the company to pay US$289 million in damages. The plaintiff, Dewayne Johnson, had used Roundup in his job as groundskeeper in a California school district. He later developed non-Hodgkin lymphoma. The jury awarded Johnson $39 million in compensatory damages to cover pain, suffering and medical bills due to negligence by Monsanto, plus an additional $250 million in punitive damages.

Today, nearly 40 percent of U.S. adults and 21 percent of youth are obese. This trend is on the upswing and the worldwide population is becoming more obese – which is increasing the risk of other conditions like Type 2 diabetes and cardiovascular disease whose prevalence has doubled globally in the last 30 years. But you may be surprised to learn that it’s not just food that is making us fat.

During recent summers, children living on the West Coast of Canada have been breathing some of the most polluted air on record. This is due to seasonal wildfires, which have burned through vast zones of North America and affected even larger areas with their smoke.

As you pack your bags for the cottage or campground this weekend, don’t forget to bring light clothes with long sleeves — and a truckload or two of insect repellent.

The health risk presented by air pollution depends on how much dirty air we breathe over time. But people’s exposure to pollution can vary greatly between people living on the same street, or even the same house.

Humans have built high-rises since ancient Roman times, but it wasn’t until the 20th century that they became the default work space for a significant slice of the world’s workers. While these buildings are certainly efficient, they can cause real health issues.

Runoff from melting snow carries road salt into streams and lakes, and causes extraordinarily high salinity.

Antibiotics are losing their ability to kill bacteria. One of the main reasons for the rise in antibiotic resistance is the improper use of antibiotics, but our latest research shows that the ingredients in commonly-used weed killers like Round-up and Kamba can also cause bacteria to become less susceptible to antibiotics.

Infectious diseases are spreading faster due to warmer temperatures, hunger and malnourishment is worsening, allergy seasons are getting longer and sometimes it’s simply too hot for farmers to tend to their crops. But what would happen if we treated climate change as a health problem rather than an environmental one?

The higher the level of particulates in the air, a new study shows, the greater the indications of psychological distress. Where a person lives can make a big difference to health and quality of life. Every increase in pollution of 5 micrograms per cubic meter had the same effect as a 1.5-year loss in education.

What substances in wildfire smoke are most dangerous to human health? What kinds of impacts can they have? Is a brief exposure, say for a few hours, dangerous, or is smoke mainly a concern if it lingers for days?

New sales of petrol and diesel cars will be banned by 2040 in the UK; France. Sweden and Scotland by 2032; Norway by 2025. Coupled with increasing concern over the carcinogenic effects of diesel emissions, the Volkswagen defeat device scandal, and the link between diesel particulates and Alzheimer’s, focus has turned again to electric cars.
