Every year, major health problems result from hazardous waste. Increasing amounts of hazardous waste have caused increasing health problems. There are over 80,000 chemicals in existence, and many are used commonly in industrial processes. Often, these chemicals find themselves ain places where they are able to harm human health. Insufficient research has been done to provide data on the effects of every chemical. Because waste chemicals often mix together, it will also be necessary to learn how combinations of these chemicals affect human health. To compound the problem created by a lack of knowledge, 1,500 new chemicals are invented every year and many are introduced into industrial processes.
Toxicity
Toxicity is the quality, relative degree, or specific degree of being toxic or poisonous, which is capable of causing injury or death through ingestion, inhalation, or absorption. Some toxic substances are known to cause cancer (carcinogens), genetic damage (mutagens), and fetal harm ( teratogens ).
Acute effects
Effects that are felt soon afterwards exposure, usually within 24 hours and in some cases almost immediately characterized by severe symptoms with a sudden onset. Skin burns and disfigurement from splashing battery acid, fire caused by an exploding aerosol can stored too close to a stove, or an overnight fish kill resulting from dumping toxicants down the storm sewer are examples of acute dangers caused by hazardous products.
Chronic effects
Effects that are gradual and occur through repeated exposure over an extended period of time. Headache and trouble thinking caused by carbon monoxide leaking from an appliance, allergic reactions that occur each time you open the cupboard where aromatic cleaning products are stored, or the slow pollution of ground waster resulting from the disposal of small amounts of herbicide down a sinkhole every growing season are examples of chronic dangers caused by hazardous substances. Some of the most common chronic health effects are liver or kidney damage, central nervous system damage, cancer and birth defects.
Long term hazards
• Risks to the environment, plants, animals and humans through long run or repeated exposure and through accumulation of toxic substances: Carcinogen, reproductive toxin
• Accumulation of toxic substances in water bodies, groundwater and soil posing a long-run risk to agro- and aquaculture

Thanks a lot! None of this is useful info!!!!! Man right something good. :0
can you explain further the causes of hazardous waste? thanks
This is not reliable.
