The way I understand it, wetlands have a lot of trees. Trees and other plants absorb carbon dioxode (what humans breath out) and emit oxygen (what humans breath). This is why people have fewer Allergies and are generally healthier whe they have large leafed house plants in their homes. There are 2 parts to this question. The plants in the wetlands use the nutrients and thus sequester them. Wetlands, as are most environments, are full of bacteria. Many of these bacteria perform specific functions; some fix nitrogen (nutrients), while others perform functions such as breaking down heavy metals (toxic wastes). Studies at the Colorado School of Mines have shown that constructed wetlands can remove heavy metals from streams ("acid mine drainage"), a big problem in the Rocky Mountains.
Pollutants, toxic materials and chemicals
Yes, toxic waste is classed as toxic (dangerous to the environment).
Butterflies remove waste the same way most other living organisms removes waste. After eating and digesting nutrients, the butterfly excretes or defecates.
The blood or the circulatory system carries oxygen and nutrients to the tissues and removes waste from them
Toxic waste is made from the bi-product of construction, manufacture and farming waste to name a few. Toxic waste is harmful to the environment and possibly to humans.
Toxic waste can be released from a great many different things. Toxic waste can be released from factories for example.
What toxic waste? Some toxic waste gives off radiation, some doesn't
In toxic waste factories
You can get it on the toxic waste candy official site.
When a microbe enters a body its still needs to feed, so it feeds on what is available, the animals cells and nutrients. And of course the microbe has to get rid of that food and sometimes its waste can be toxic. It is this toxic waste substance that cause the disease.
Toxic waste can be helpful in a very few special situations. Toxic waste can be used to kill unwanted organisms.
