Industrial wastes (pharma, labs, chemical) City sewages and waste water spill outs even when there is traditional water treatment* Xenobiotics Such pollution is widely spread Agriculture chemical pest treatment run-offs into ground water reserves, rivers or lakes accessed for water consumption as drinkable water for human beings, animals and agriculture (crops and orchards…) Rivers Lakes Ground Water Ocean * An Indian Survey numbers the cities with real water drainage systems (even traditional or archaic) as… Wells Rain
4. Xenobiotics accumulate in living organisms. The higher in the food chain the more contaminated and at risk you are of getting heavier doses; the heavier the dose, the more lethal. Xenobiotics Contamination of the food chain Xenobiotics do not get eliminated easily ! Xenobiotics have been proven to transfer into crops, vegetables and fruit ** (** …)… At least as for heavy metals like mercury, there is bioaccumulation ! WORSE !
5. Indirect Human Contamination First level Vegetarian consumption is, alas, not sufficient protection crops and orchards watered with polluted water vegetables, cereals or fruit raised using as fertiliser sludge from sewage treatment units or non composted (although compost cycle has not been proven to eradicate xenobiotics contamination) contaminated by human or animal dung Direct Human Contamination From drinking water collected from polluted ground water reserves, wells, drinkable water plants, rivers or lakes accessed as drinkable water for human beings; Chemically pest treated non washed vegetables, cereals or fruit Indirect Human Contamination Second level Non Veg consumption is typically cumulative (cf for Food Chain accumulation - slide 52) Meat from animals fed on polluted water, contaminated grass or crops or feed based on contaminated animal and vegetal origins Fish, snails, shrimps (aso) from aquaculture or in the wild in polluted river beds, lakes, seas and feeding on contaminated plants, plancton, crustaceans or smaller fish… Indirect Human Contamination Third level Milk from contaminated dairy cows, goats… Giving Birth [ ] Xenobiotics Human Contamination Xenobiotics in Waters Xenobiotics in Foods
