Well,

You can test DO, CH4 , TN(NO2,NO3), NH4, NH3 , also you can test a reference soil or water samples(samples far away from polluted site), correlated with samples taken from polluted site, Here, different concentrations between reference samples and expected polluted samples, can be indicated pollution phenomenon.

I see no reason to test for lead. In my opinion there is no link between an abattoir and lead.

If present in feed, it will predominantly end up in bones.

Environmental pollution is more likely to be due to lead containing paints, gasoline etc or abandoned batteries.

Dear Olugbenga

If you want to know the impact of the contamination of slaughterhouse wastewater, you can carry out the following tests:

* pH (these waters are usually are mixed with the washing waters of the viceras and you have a pH above (basic, due to the use of alkalis for washing the viceras) the maximum permissible limit by the WHO).

* COD and BOD are fundamental parameters that you must monitor to determine the concentration of organic matter and therefore measure the degree of contamination of a body of water (the main factor causing decreased dissolved oxygen, anoxia and death of the aquatic ecosystem).

* Nutrients such as Nitrogen (total, NO2, NO3, NH3) and phosphorus are also required since they are the main cause of eutrophication.

Lead is bioaccumulable in the body of the animal, so I do not see the reason why to determine it. however as these waters are mixed with the blood of the animal can exist if it is in high concentrations in the animal, so you could find slight traces of lead in your waters, it would be interesting to see or compare if they do not exceed the LMP.

Olugbenga Elemile: According to my opinion it is also necessary to rest for microbiological parameters, especially fecal colifom bacteria, Salmonells, other potrntially pathogen microorganisms. The reason is that abatoir pollution contains a huge load with potentially risk microorganisms.
