Residual nitrite levels in Philippine sweet bacon
Abstract This study established the residual nitrite (NO 2 ) levels in Philippine sweet bacon, tocino , prepared by micro- and small-scale meat processors from Pampanga, Philippines. The NO 2 levels in the tocino samples ranged from 0.76 to 12.00 and 12.20 to 144.42 mg NO 2 /kg tocino from micro- and small-scale processors, respectively. Generally, the NO 2 levels found in tocino samples analyzed were below the Philippine recommended residual NO 2 value of 125 mg/kg in cured meat products.
Objective To evaluate the effect of the post-processing mode of sewage treatment in two rural areas of Shengzhou and to provide scientific basis for rural toilets renovation.Methods Ten sanitary toilets of three cesspools and four cesspools for each were random selected.The basic situation,routine monitoring and pollutant items were evaluated.Results Routine monitoring items basically reached the sanitary standards and ammonia,COD,BOD5 qualified rate is low.The results of ammonia,phosphorus,COD,BOD5 in three cesspool sanitary toilets significantly better than that of four cesspool sanitary toilets.Conclusion Part of hygiene and pollution item removal rate and qualified rate are low.Harmlessness effect of tree cesspool toilets is better than four cesspool toilets.It is necessary to strengthen design,technical guidance and check in construction of rural toilets.
