292 words
TOPIC RESEARCH Lead is one of the most harmful, but yet most unexpected air pollutants in the world today. For many years Lead has been known as a poisonous substance, nevertheless still to be ignored by some. Lead does a large amount of damage to the human body. And the bad thing about it is that if I had to name some of the most harmful air pollutants in the world I probably wouldn't have even mentioned lead.
Lead is very harmful to the human body. High levels of exposure to Lead can damage the blood, brain, nerves, kidneys, reproductive organs, and even the immune system. While on the other hand lower levels which are more commonly associated with current exposures can result into impaired mental functioning and development in children and raising blood pressure in middle-aged men. What makes lead even more dangerous is that it accumulates in the body so bad that even small doses can be harmful to the body.
Some of the remaining sources of lead pollutant includes lead smelters, incineration of lead batteries, and burning lead-contaminated waste oil. However, the most common sources of current lead exposure are indoors from old lead-containing paint and soil. Many actions are being taken in effort of reducing lead air pollutants, but there still can be even more things done to help reduce this problem that is affecting the people in the world that we live in. And it all starts with everyone looking at themselves first.
One plus is that due to major reductions and now the elimination of lead in the world's gasoline, there has been a significant decrease in public exposure to lead in outdoor air.

Boyi Zh.

As probably any student, I was quite hesitant about asking somebody else to do my assignments at first. However, after EssayPride has sent me my first paper and I've read it, I understood that I could actually learn a lot from them. The research they've done was impressive and I understood the topic even better than after going to class and reading my textbook. I am not using this website to "cheat", I am using it as a tutoring service, they help me to understand the material better.
