Short term repeated exposure of 1-chloroacetophenone (CN) vapours at a concentration of 0.153 mg per litre for 15 minutes daily on 10 consecuitve days in Swiss albino male mice resulted in increased mortality to Listeria monocytogenes. Significantly elevated bacterial growth was observed in the spleen and liver of the CN exposed animals. The increased bacterial count in these organs was evident within 4-6 days post challenge as compared to vehicle exposed infected and unexposed infected animals. Increased susceptibility to infection has been considered to be the function of immune alteration due to cumulative short term effects ofCN vapour inhalation. This may be attributed to immunotoxic effects of CN on Tcells mediated macrophage functions.

Sensory irritation of the upper respiratory tract was induced in mice by inhalation of vapors, generated under thermal stress of two tear gases viz. 1-chloroacetophenone (CN) and dibenz (b, f)-1, 4 oxazepine (CR) following a simple exposure technique. A known quantity of the irritant was kept in an adapter fitted with glass exposure chamber, heated, and the vapor thus generated was purged into the chamber. The restrained mouse inhaled the vapor, and the resultant depression of respiratory rate was recorded on a polygraph. Fifty percent depression of the respiration rate and the corresponding air concentration of the irritant was determined by obtaining the linear curve fitting equation and putting the value of Y=50. It was concluded that inhalation of CR vapor was 2. 66 times more irritating than that of CN in mice. The employed exposure method also proved to be simple, sensitive, easy t0 operate,and may also prove useful in evaluating irritation of upper respiratory tract fOllowing the inhalation of vapors of various chemicals.

Sewage sludge is a good source of energetically desirable compounds and green algae in developing country like India. In this work, the combustion characteristics of sewage sludge and green algae are described. The calorific value (CV) of dried sewage sludge (n = 7) and green algae (n = 11) was ranged from 1800 to 6250 and 3700 to 6280 kcal/kg with mean value of 3999 ± 1347 and 4428 ± 547 kcal/kg, respectively. The effect of proximate variables and water quality parameters in the CV of sludge and algae are discussed.

A huge amount of waste from the cattle livestock and bird poultry are generated using as manure and solid fuel. In this work, the heat value and proximate parameters of livestock and poultry manures are described. The calorific value of manures (n = 22) was ranged from 2580 - 11,200 kcal/kg with mean value (p = 0.05) of 5333 ± 1073 kcal/kg. The effect of cattle age and additives i.e. NaNO3 and Na2WO4 in the heat value of the manures are discussed. The chemical characteristics of the emitted particulate matters (PM) and ash residues are highlighted.

Mycobacterium avium subsp. paratuberculosis causes chronic inflammation of the intestine known as Johne’s disease (JD) in domestic and wild ruminants including primates. MAP has also been associated with inflammatory bowel disease (IBD) so called Crohn’s disease (CD) of human beings, which is incurable even after surgery. By virtue of the pasteurization resistant power, high endemicity of the infection in animals continues to be the permanent source of infection to human population. High bio-burden of MAP in wide range of biotic (animal hosts including human beings) and abiotic environment in each and every country where it has been investigated, serves a reminder about the survival abilities of the MAP in diverse range of environmental conditions. Ability of the MAP to evade immune system of the host and the temporal events during infection of the macro-phages, is an area of major concern and research activities as the pattern of distribution are quiet different from those of other pathogenic intracellular organisms. Moreover, the organism can survive over a wide range of environmental conditions such as high and low environmental temperatures, pasteurization, low pH, and high salt concentration etc. This superior survival efficiency from environmental degradation and dormancy within host allows the pathogen to be available for causing disease and pathogenicity in animals and human beings, when conditions are favorable. Perusal of literature reveal that, despite the availability of whole genome sequence of MAP, a very little is known about the replication, persistence and survival mechanisms of this pathogen. Therefore, this review tries to address the survival mechanisms of Mycobacterium avium subspecies paratuberculosis in the different host species and adverse environmental conditions in order to allow designing of more rational diagnostic and control procedures.

In country like India, the groundwater is widely used for drinking purposes. In central India, the groundwater is hard and contaminated with F- and other elements above the permissible limits and found to be linked with prevalence of the fluorosis diseases. In this work, the groundwater quality Balod district, Chhattisgarh, India is investigated for assessment of water quality for drinking purposes. The concentration (n = 50) of F- was ranged from 1.5 - 14.0 mg/L with mean value of 3.9 ± 0.8 mg/L. The causes of prevalence of skeleton fluorosis in human of the studied area are described.

Journal of Water Resource and Protection 2016年第1期8卷 12-19页

The groundwater is widely used for irrigation of rice crops. The overuse of groundwater causes depletion of the water quality (i.e. enormous increase in conductivity, hardness and ion and metal contents, etc.) in several regions of the country and world. In this work, the quality of the groundwater in the densestrice cropping area, Saraipali, Chhattisgarh, Central India is discussed. The water is sodic in nature with extremely high electrical conductivity. The mean concentration (n = 30) of F-, Cl-, NO3-, SO42-, NH4+, Na+, K+, Mg2+, Ca2+ and Fe in the water was 1.2 ± 0.2, 98 ± 31, 46 ± 15, 56 ± 9, 19 ± 4, 206 ± 25, 9.2 ± 2.3, 39 ± 6, 114 ± 19 and 1.7 ± 0.6 mg/L, respectively. The sources of the contaminants are apportioned by using the factor analysis model. The suitability of the groundwater for the drinking and irrigation purposes is assessed.
