Abstract: |
A total of 150 samples,
representing 75 samples of dairy product that produced in
farms and dairy factories local and 75imported samples, All
samples were collected from different supermarket in Amman
city of Jordan, and analyzed for aflatoxins M1 (AFM1) using
Enzyme-Linked Iimmunosorbent Assay (ELISA) The results
showed that the percentage 14% of raw milk samples, 20% of
full cream milk UHT, 10% of whole milk powdered and 30%
skimmed milk UHT were contaminated with AFM1, with an
average concentration of 5.82 10.72 ppt, 16.81 1 1.08ppt,
6.89 1 1.05ppt and 39.5 1 1.45ppt, respectively. 12.66 % of
imported samples (11 samples) and 12% (9 samples) of Samples
that locally produced were contaminated with AFM1.
Evaporated milk, low fat milk UHT (1.5%) pasteurized milk
and yogurt zabadi were free of Aflatoxin M1. |

Abstract: |
Several environmental and
health problems caused by industrial and domestic wastewater
were identified scientifically decades. Slaughterhouses are
probably typical example of those industries where water is
used for washing by-products (offal) and the disposal of
waste (feces, debris paunch and blood).Our main objective is
to characterize the wastewater from the municipal
slaughterhouse in the city of Rabat, in order to recommend
appropriate treatment to their reuse, reducing their impact
on the receiving environment (the Atlantic coast) and enjoy
this rich water source into reusable materials. The
physicochemical characterization of raw sewage revealed
significant organic matter load varying between 668 mg/L and
1203 mg/L. The TSS concentration wastewaters analyzed vary
between 603 mg/L and 1068 mg/l with an average of 835 mg/L.
The temperature of the water remains below 300.The pH is
relatively neutral, whereas the electrical conductivity
varies between 590 microseconds/cm and 1910 microseconds/cm.
The turbidity varies between 590 and 1384 NTU. The mean
levels of nitrates and Orthophosphates respectively of the
order of 2.65 mg /Let 0.1mg/L. This wastewater has a high
organic load in terms of COD that varies between 960 and
2018 mg O2/l and BOD5 fluctuates between 470 and 960 mg
O2/l. However the COD/BOD5=2.20, indicating a satisfactory
biodegradability of these releases. Biological treatment
therefore seems entirely appropriate to their reuse one hand
and reducing their impact on the receiving environment (the
Atlantic coast). Analysis of heavy metals from wastewater
from the slaughterhouse of Rabat, show relatively low
concentrations do not exceed 0.5 mg/L. These values meet
Moroccan standards of water quality for irrigation. |
