Some industrial wastes also contain pathogenic bacteria, which cause significant health hazards.
For example, the pathogen Anthrox bacilli are present in tannery waste. The dumped urban wastes along highways and other places in cities spread several chronic diseases posing a serious threat to human health.

However, rapid urbanization, agricultural modernization and industrialization have resulted in a number of complex inorganic and organic byproducts which are non-biodegradable or persistent resulting in the disruption of natural eco-system.
According to Berry , improper disposal of solid wastes create conditions for a wide range of diseases such as cholera, typhoid, hepatitis, conjunctivitis, entamoebiasis, poliomyelitis, round worms, hook worms, and many more.
