Bacterial Load In Drinking Water Supplied At Different Private Hospitals In Dhaka, Bangladesh 2020-03-23T20:05:33+00:00 Md Abdul Karim Most Shermin Naher Keya <p>Water samples supplied in different private hospitals of Dhaka city, Bangladesh were collected for microbiological analysis. The hospitals were Ibrahim Memorial Hospital (B1RDEM), Lab Aid Hospital, Gonoshasthaya Nagor Hospital, Ibn Sina Hospital and Japan Bangladesh Friendship Hospital. Aerobic heterotrophic bacterial count ranged between 1.8 * 10<sup>4</sup> and 4.6 * 10<sup>4</sup>cfu/100 ml. Enteric and related bacterial abundance in MacConkey, SS and Cetrimide agar media ranged from 0 to 7.6 * 10<sup>4</sup>, 0 to 3.4 * 10<sup>4</sup> and 0 to 2.2 x 10<sup>4</sup> cfu/100 ml, respectively. A total of 27 bacteria was isolated during the study period. Among them 19 were heterotrophic and 8 were enteric and related bacteria. Among the heterotrophic isolates 14 were gram-positive, of which 13 were rod shaped, spore former under the genus Bacillus viz. Bacillus circulans, B. fastidiosus, B. badius, B alcalophilus, B. brevis, B. lentus, B. firmus, B. subtilis and another one was coccus as Planococcus. Five heterotrophic gram-negative isolates were under the genus Pseudomonas and Aeromonas All enteric and related isolates were gram-negative, short rod and non-spore former and belong to genera Salmonella, Shigella, Klebsiella Pseudomonas and Escherichia.</p> <p>Asiat.

Two concentrations of NAA, 100 and 200 ppm were used as foliar spray. In BRRI dhan 29, significant increases in chlorophyll a and chlorophyll b contents of leaf were observed due to both the treatments at the flowering stage, whereas, carotenoids at the grain filling stage only. But in BRRI dhan 50, the total leaf pigments decreased at the flowering and grain filling stage, but was significant in case of chlorophyll a at the flowering stage. Significant increases in protein content of leaf were recorded at the tillering and flowering stage of BRRI dhan 29 following 100 ppm NAA treatment. In BRRI dhan 50, the only significant increase was recorded at grain filling stage due to 200 ppm NAA treatment. In both the varieties carbohydrates, protein, fat, and energy content of grain increased due to both the treatments and the maximum increase in all the cases was recorded due to 100 ppm NAA treatment. Ash and moisture content of grain reduced following both the treatments in both the varieties, the maximum reduction was due to 100 ppm NAA treatment</p> <p>Asiat. Soc.

The prevalence of underweight decreased and the prevalence of overweight increased with the increase in the age of reproductive women. Fifty-nine percent of adolescent women (aged 15-19 years) were underweight. The level of education was negatively associated with being underweight but positively associated with being overweight or obese. Of 3,472 illiterate women, about 59 percent were underweight, and of 847 higher-educated women, 37% were overweight. The poor women were three times [odds ratio (OR) =3.22, 95% confidence interval (Cl: 2.73-3.81)] more likely to have underweight or malnutrition compared to women of high socioeconomic status, and rural women were slightly (OR=1.10, 95% Cl: 1.00- 1.22) more likely to have underweight or malnutrition than those of urban. The housewives or unemployed women, were almost two times (OR=1.55. 95% Cl: 1.33- 1.80) more likely of being overweight or obese than the w orking w omen. The findings of this macro-level study of public-health issue will help the Government and planners to take sustainable policies for improving the reproductive women's health.</p> <p>Asiat. Soc.

The NNPs were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) spectroscopy and X-ray diffraction (XRD) techniques. The addition of PVA has been found to profoundly influence the size, agglomeration and distribution of NNPs. The average diameters of NNPs are in the range of 3-7 nm in presence of PVA. XRD data indicate that NNPs are crystalline with face centered cubic structures. SEM images show the existence of secondary structures such as clusters and loops resulted from interactions between particles. The sizes of the NNPs were by and large uniform due to the use of PVA as the capping agent. FT-IR and thermogravimetric analyses confirm the interaction of PVA w ith NNPs to offer improved thermal stability</p> <p>Asiat. Soc.

The depth of these dug wells varies from 3.4 to 16 m with an average depth of 10 m with diurnal variations. The hydrochemical classification shows that the dug well and Buriganga river water samples are Ca-HC03 type. More than 50% dug well water samples were contaminated as concentration levels of Ca, K and Fe in both periods were high whereas over 25% Buriganga river water samples were tainted as concentration levels of Ca, Mg, Fe and Mn in dry season exceeded the drinking water quality standard limits of World Health Organization (WHO), Department of Environment (DOE) and United States Environmental Protection Agency (USEPA). If the dug well water is protected from contamination, the shallow groundwater in this part of Dhaka city should be an alternative perennial source of water especially during the dry season when water scarcity looms large</p> <p>Asiat.

Besides, lack of skilled lab teachers or trainers is also a constraint for practicing ICT. Albeit, there are multimedia facilities in most of the selected schools but currently only the RAJUK Uttara Model College of Dhaka Metropolitan Area uses this system properly. However, in recent times, only the students of eight renowned schools of the study area can access the E-book (science textbooks) facility system from different government websites but unable to utilize the service properly due to inadequate and slow internet support system.</p> <p>Asiat.

The fits are quite satisfactory over practically the entire angular range and the best fit parameters are obtained. These are used for the study of the inelastic scattering of alpha particles leading to the collective states in nuclei. A reasonably good fit is obtained without any adjustment of the parameters suggesting thereby the success of the strong absorption model.

The results reflected slight contamination of some of the water samples with residues of diazinon, chlorpyriphos (organophosphorus insecticide), carbaryl and carbofuran (carbamate insecticide). The concentration of diazinon and chlorpyriphos ranged from 2.31 jig/L to 5.60 pg/L and 0.0 to 3.80 pg/L respectively. Among carbamate pesticides, carbofuran identified in two samples, ranging from 1.40 to 3.71pg/L, carbaryl was detected in two of the samples which ranged from 1.32 to 6.40pg/L, and pyrethroid (cypermethrin) was not detected in any of the samples. However, the residue level was also within the acceptable ranges according to the WHO guideline value (1993) of water quality. But, its presence in surface water as WHO-recommended limits is a matter of concern. In Bangladesh consumption ofpes::c.Jcs has been increased with the introduction of high yielding varieties of rice in recent years But. the widei&gt; cultivated high yielding variety is highly vulnerable to pests and diseases, and 40; : of the crop loss can be attributed to attack by pests and insects in Bangladesh which is a significant loss (Bagchi, et al. 2008). So, the use of pesticide is now an integral part of agriculture for pest control. More than 100 species of insects, 600 weed species. 1500 plant diseases and 1500 species of nematodes are being controlled by pesticide (Brady 1990). As a result, the production of improved variety of rice has significantly increased in recent years. Although pesticide is beneficial for pest control, it also poses a harmful effect to our environment such as the pollution of surface and ground water. After application of pesticide in the crop field it is degraded in the soil by the soil microorganism to some extent but many of the toxic pesticides are transported into surface and ground water by agricultural run off rain water from the crop field. Ultimately, the surface and ground water may be highly contaminated due to this agricultural run off pesticide (Bagchi, et al. 2008).</p> <p>Asiat. Soc.
