Each 10 microgram per deciliter rise in lead levels lowers intelligence levels by four to seven points on IQ tests, according to the U. Many of these problems, including untreated sewage and urban air pollution, have either been solved or diminished in the developed world, and there's no reason they couldn't also be solved in the developing world, Fuller says.

Mercury vapor, for instance, once burned off by the artisanal miners can drift high into the atmosphere where it crosses continents and even oceans before settling back to the ground.

Once in the food chain it bio-accumulates increases in concentration as it passes up the chain from plant to plant-eater to meat-eater until it reaches top concentrations in predators such as tuna fish.health outcomes, including many of the outcomes for which there are cross-national health differences, such as noncommunicable diseases, associated risk factors, injuries, and violence.

The environmental impact of aviation occurs because aircraft engines emit heat, noise, particulates and gases which contribute to climate change and global dimming.

Airplanes emit particles and gases such as carbon dioxide (CO 2), water vapor, hydrocarbons, carbon monoxide, nitrogen oxides, sulfur oxides, lead, and black carbon which. For starters, one of the biggest environmental issues we are currently facing is overpopulation.

With a direct impact on our food production and other important factors, overpopulation is one of the leading causes.
