Background: In recent decades, imported boneless and frozen beef has invaded the Algerian market. However, the true appreciation of the quality of this product can only be obtained by laboratory analyzes and examinations. Aims: The aim of the current study was to assess physicochemical parameters of the imported boneless and frozen beef meat dedicated for human consumption. Methods: Twenty (20) samples of neck, blade bolar, brisket, blade oyster, Forequarter (FQ)/hindquarter (HQ) shin-shank were purchased from the Regional Meat Office in Saida city, Algeria. Physicochemical parameters such as pH, water, ash, protein and fat content were analyzed according to standard procedures. Results: Our results showed a highly significant variability concerning protein and fat content of the five categories of analyzed pieces (p=0.002). Fat content ranged from 0.43g to 4.04g per 100g of edible portion, for which we found low intramuscular fat contents in the lumps. However, the pH values obtained generally characterized RFN (Red, Firm, and Normal) meat. Conclusions: In view of the results obtained from this study, the overall chemical composition is satisfactory, except for the fat content which constitutes a parameter to be discussed and which depends on the taste of the consumer. Keywords: Frozen meat, analysis, physicochemical quality.

The catchment area of River das Antas (Irati, Paraná, Brazil) is of high importance both for human consumption and irrigation. Within Irati, this river passes through a rural area and through the city of Irati, crossing both poor and rich neighbourhoods. We selected three study areas downstream (a rural area, poor community, and rich neighbourhood) in which we measured turbidity, the concentration of sediments and pH during rainy days. Our results showed downstream trends of increasing turbidity and concentrations of sediments with decreasing pH. The values of turbidity and of concentration of sediments were significantly different in the rural area, while the pH values were significantly different between the three study areas. These findings highlight the effect of agricultural activities in the generation of sediments and turbidity. The—presumably expected—effects of organic urban waste from the poor neighbourhood were also detected in the pH values. We conclude that efforts should be made to ensure that land planning and training/education programmes on sustainable farming practices are undertaken by the authorities to reduce water pollution and its effects on water bodies during rainfall events, since paving streets is not a feasible option in the short term due to the high costs associated with this measure.

The present study was aimed to analyze the influence of industrial and agricultural wastes on quality ofKosi river water, Rampur, UP, India. The results of the present study revealed pH values of between 7.2 and 6.3 (neutral to slightly acidic), the electrical conductivity between 129.4 μs/cmto399.3 μs/cm. The maximum EC value was observed at S5 in spring season. The turbidity of each was 0.4 to 7.067 NTU. The highest turbidity observed at S5 in winters. Total hardness of 73 (mg/L) and 506.33 (mg/L) were evident at S4 and S7 sites respectively. The BOD values ranged from 10.5 (mg/L) at S4 to 137.4 (mg/L) at S5. Higher BOD values at each site are reflecting the great extent of pollution. The minimum COD recorded at S3 (32.60 mg/L) however maximum recorded at S5 (168.65 mg/L). The results of the heavy metals showed a significant increase in the concentration of Pb, Zn, Cu, Hg and As at S5 as compared to the other sites. The As concentration was 0.04, 0.08, 0.85, 0.72 and 0.71 at S2, S3, S5, S6, and S7 respectively. These values were higher than the value of Arsenic as per WHO guidelines.The average concentration of Zn obtained was 0.05, 0.786, 0.413, 0.06, 3.26,0.97 and 0.53 mg/L at S1, S2, S3, S4, S5, S6, and S7 respectively. The highest value of Zn was recorded at S5 (SDP) as compared to other sites. Only at S5 the zinc content is exceeding the normal value. The copper content found to be lower (1.0 mg/Ll) than permissible value according to WHO. The Cu concentration was 0.01, 0.06 0.01 at S4, S5 and S6 respectively, at S1,S2, S3 and S7 zero. The changed physicochemical parameters and occurrence of heavy metal ions indicated a significant level of pollution in Kosi River.

A study was carried out with the objective of evaluating the microbiological and physicochemical quality of surface water in the  Nkolafamba subdivision, Center Region of Cameroon. Five sampling points were selected based on several criteria. The bacteria isolated were Mesophilic Aerobic Heterotrophic Bacteria (BHAM), bacteria that were witnesses to faecal contamination and Pseudomonas. Some abiotic parameters were measured using the usual techniques. The results show that some physicochemical parameters such as temperature was almost constant around 25 °C during the study period. There is also a pH which tended towards neutrality pH de (7,04 ± 1,03 U.C). However, it was noted that the stations are quite oxygenated (63,96%). Bacteriological analyzes revealed that an average value of 5.17 units (logUFC / 100mL) was recorded for BHAM. Overall, the abundances of total coliforms averaged 4.18 units (logUFC / 100mL). The waters of Nkolafamba also harbor a pathogenic microflora, with bacteria such as P. aeruginosa P. pasteurella, the abundance of which can sometimes reach 5,462 units (log CFU / 100mL). These germs can be the cause of eye infections or septicemia on users of these waters. These waters have a high bacterial load, and the microbiological pollution observed is predominantly animal. Some abiotic parameters such as pH, electrical conductivity, Suspended Solid (SS), nitrates and turbidity have influenced the distribution of these germs. The degradation of the quality of these waters is favoured by their proximity to sources of pollution, the runoff of contaminated water in the stations. These waters, without any treatment, are not recommended for human consumption according to the standards of the World Health Organization.Keywords: Abiotic variables, faecal coliforms, faecal streptococci, pathogenic bacteria, rivers.

ABSTRACT The purpose was to evaluate the effects of gender and of different genotypes of chickens on the physicochemical parameters and centesimal composition, related to the quality of meat. The design was completely randomized arranged in 5x2 factorial scheme, five genotypes (Índio Gigante - IG; New Hampshire - NHS; Gigante Negra de Jersey - GNJ; poultry from the crossing between the IG and NHS breeds - IG x NHS; and between the IG and GNJ breeds - IG x GNJ) and two genders, with five repetitions and each one represented by three poultry, totaling 150 animals, slaughtered at 105 days. The parameters evaluated on the breast and thigh were: centesimal composition (moisture, ether extract - EE, protein and ash), ultimate pH, color (L*- luminosity, a*- redness, b* -yellowness, C* - chroma index and h* - hue angle), weight loss by cooking (WLC) and shear force (SF). The IG genotype had the highest average of ultimate pH of the breast (6.03). The NHS and IG x NHS genotypes showed, respectively, higher average of L * (58.93) and a* (1.92) of the breast. The IG, IG x NHS and IG x GNJ showed the highest values of b* of the breast (12.53, 13.37 and 12.69, respectively). The IG poultry showed high average of SF of the breast and thigh (4.79 and 5.01kgf, respectively). The IG x NHS and IG x GNJ genotypes showed the lowest ultimate pH values of the thigh (6.13 and 6.02, respectively). The IG x GNJ genotype showed a high average of b* of the thigh (14.94) and the NHS had a high average of WCL (24.65%). The females showed higher averages of EE on the breast and ash on the thigh (1.03 and 1.11%, respectively). The IG x NHS and IG x GNJ poultry showed higher averages of EE of the breast (1.21 and 1.38 %, respectively). The poultry of IG breed and those from the crossing with NHS and GNJ presented meat quality characteristics more desirable by the consumer in relation to physicochemical parameters and centesimal composition, while genders showed no influence on these aspects.

The Impact

In recent years, sachet water known as "pure water" has gained the confidence of the Nigerien public because of its low price, availability, convenience, and quality perception by consumers. This study highlights the impact of storage on the quality of pure water sold in Niamey. Thus, eleven of the twelve analyzed physicochemical parameters have been monitored during six weeks of "pure water" storage in the sun and at laboratory ambient temperature. From the results obtained, the physicochemical parameters are in norms except the turbidity and the residual chlorine. On the Bacteriological plan, the total germs, the salmonellae, the fecal streptococci and the Escherichia coli have been identified. In addition, the monitoring of the evolution of the parameters analyzed during six weeks of storage revealed a change of the organoleptic quality that appears in the fourth week and a development of Escherichia Coli for the "pure water" exposed in the sun. This study showed, on the one hand, that these "pure water" would be unfit to the human consumption and on the other hand, their storage for a prolonged period and a high temperature affects their qualities. Les eaux conditionnées en sachet plastique, communément appelées "pure water", ont depuis quelques années, gagné la confiance du public nigérien en raison de leur faible prix, leur disponibilité, la commodité, et de la perception de qualité par les consommateurs. Ce travail étudie l’impact du stockage sur la qualité des "pure water" vendues à Niamey. Ainsi, onze parmi les douze paramètres physico-chimiques analysés ont été suivis pendant six semaines de stockage des "pure water" au soleil et à la température ambiante de laboratoire. A l’issue des résultats obtenus, les paramètres physico-chimiques sont dans les normes hormis la turbidité et le chlore résiduel. Sur le plan bactériologique, les germes totaux, les salmonelles, les streptocoques fécaux et les Escherichia colis ont été identifiés. Par ailleurs, le suivi de l’évolution des paramètres analysés pendant six semaines de stockage a révélé une altération de la qualité organoleptique qui se manifeste à la quatrième semaine et un développement des Escherichia colis pour les "pure water" exposées au soleil. Cette étude a montré, d’une part, que ces "pure water" seraient impropres à la consommation humaine et d’autre part, leur stockage pendant une période prolongée et une température élevée affecte leurs qualités.

Abattoir Wastewater

The physicochemical parameters of the thirty water samples collected at the point of discharge of abattoir wastewater as site A (upstream), site B  (downstream) and site C (the irrigation space) of the seasonal River Tagangu were analyzed. The parameters tested include: pH, temperature, turbidity, conductivity, dissolved oxygen (DO), biological oxygen demand (BOD), nitrate, sulphate, phosphate and ammonium. All the parameters were tested following the standard procedures. The pH values obtained ranged from 6.5–7.9; suggestive of suitability of the water for bacterial growth. The temperature values ranged from 21.2–31.2oC; falling within the WHO standard. The turbidity of the water samples ranged from 520–627 NTU, which are exceedingly higher than WHO limit. The conductivity of the water samples ranged from 42.9–624.0 mS/cm; values were far higher than 400.0 mS/cm of WHO standard. The dissolved oxygen (DO) measured between 6.9-19.0 mg/l; which is also greater than WHO standard (6.0 mg/l). Biological oxygen demand (BOD) measured between 312–527.9 mg/l; greater than WHO threshold of 10.0 mg/l. The nitrate contents varied between 39.2–72.3 mg/l; greater than WHO standard (10 mg/l). The sulphate values varied between 45.6–93.9 mg/l; falling within the WHO threshold. However, values greater than 10 mg/l, suggests that the water has been polluted. The phosphate contents observed ranged from 0.435–0.849 mg/l across the three sites, values were higher than 0.3 mg/l of WHO standard. The ammonia contents of the water samples ranged from 27.7–948.5 mg/l; far greater than 0.5 mg/l of WHO standard. The physicochemical study across the three (3) sites shows the typical pollution of the river and rendered the quality of the water hazardous to humans, animals and aquatic lives that could be the users of the water.

Water quality is closely linked to water use and to the state of economic development. Water pollution occurs when unwanted pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Water pollution affects plants and organisms living in water bodies and also to the natural biological communities. The present study is to assess the quality of river Khan at Triveni, Ujjain. Khan River flows from Indore via Sanwer it reaches Ujjain and joins Kshipra at Triveni. There are several industries in Indore, which throw their effluents in the river and it receives untreated sewage, drainage, run off from farms from the villages which are situated at the bank of this river. Though Bhangarh treatment plant has been setup at Indore to treat river Khan, only 30% of the river is being treated while rest of the water is untreated. Hence this source has been rendered unsafe for human consumption.
