Carbon dioxide (but not from nuclear plants)
Carbon dioxide can be considered both an air pollutant due to its role in climate change and a beneficial chemical as it is essential for photosynthesis in plants, which is the basis of the food chain.
Computer manufacturing or Chemical Plants
Salt is considered a pollutant in soils because many plants does not support salted soils.

water is used in industries in preparing many of the chemical substances and in agriculture it is used for planting crops and irrigation purposes and for providing water for photosynthesis in plants.
In Canada, at least, you can search the National Pollutant Release Inventory (NPRI) to determine the levels of any specific pollutant from any area. Your local environmental control agency may have a similar searchable database.

The food making process in green plants is photosynthesis. During photosynthesis, plants convert light energy into chemical energy that is later released to fuel the plant's activities.
A herbicde is a chemical that kills plants (wedkillers etc.). Herbicides are generally manufactured by chemical industries, not grown as crops. Herbicides are used worldide for peaceful (pest control) and war oriented (defoliants) purposes.
