Harmful Effects

Against rapidly developing industry and increasing population, natural resources on earth are getting destroyed. One of the most important adverse effects on the environment is perhaps the depletion of ozone layer which protects the earth from harmful effects of UV radiation, especially UV-B. The effect of UV-B radiation can vary according to species. At high rates of UV-B radiation, many disorders in DNA, photosynthesis, morphological and physiological structure, and biomass accumulation in plants are observed. In this review, the effects of high UV-B radiation on terrestrial ecosystem are discussed.

Background: Previously considered safe for typical use, concerns have recently been expressed regarding the potential effect of compact fluorescent lamps (CFLs) on human skin and, in particular, on skin cancer risk. Objective: We sought to address this concern by reviewing the current literature on CFLs, ultraviolet (UV) radiation, and photocarcinogenic exposure. Results: On average, the UV radiation from CFLs and subsequent carcinogenic exposure is lower than that from incandescent bulbs. However, defective bulbs can emit higher levels of UV radiation, which may cause significant damage. Conclusion: Our review calls for further investigation to determine how frequently these bulbs are sufficiently defective to lead to adverse effects.

Overpopulation has recognized as a global environmental problem since few decades, as it has caused a number of adverse effects on environment. Modern medical facilities and illiteracy in some interior regions of developing countries are the major reasons for development of this inverted pyramid demographic structure. Overpopulation has resulted in a series of catastrophic consequences by causing increased pressure on existing natural resources. Deforestation, effect on welfare, climate change, decline in biocapacity, urban sprawl, food security, increase in energy demand and effect on marine ecosystem are amongst most severe impacts of overpopulation. Concrete steps need to be taken on national and international level to combat the adverse effects of overpopulation, so that sustainability of natural resources can be ensured for future generations.

The skin is the outermost protective barrier between the internal and external environments in humans. Chronic exposure to ultraviolet (UV) radiation is a major cause of skin aging. UVB radiation penetrates the skin and induces ROS production that activates three major skin aging cascades: matrix metalloproteinase- (MMP-) 1-mediated aging; MAPK-AP-1/NF-κB-TNF-α/IL-6, iNOS, and COX-2-mediated inflammation-induced aging; and p53-Bax-cleaved caspase-3-cytochrome C-mediated apoptosis-induced aging. These mechanisms are collectively responsible for the wrinkling and photoaging characteristic of UVB-induced skin aging. There is an urgent requirement for a treatment that not only controls these pathways to prevent skin aging but also avoids the adverse effects often encountered when applying bioactive compounds in concentrated doses. In this study, we investigated the efficacy of genetically modified normal edible rice (NR) that produces the antiaging compound resveratrol (R) as a treatment for skin aging. This resveratrol-enriched rice (RR) overcomes the drawbacks of R and enhances its antiaging potential by controlling the abovementioned three major pathways of skin aging. RR does not exhibit the toxicity of R alone and promisingly downregulates the pathways underlying UVB-ROS-induced skin aging. These findings advocate the use of RR as a nutraceutical for antiaging purposes.

Ultraviolet (UV) radiation is the main cause of sunburn and skin cancer. The adverse effects of UV radiation are solved by sunscreen as protection for longer outdoors. In this study, optimization of glycolic acid and citric acid in sunscreen cream combination of titanium dioxide, avobenzone, and octyl methoxycinnamate were investigated using simplex lattice design method. The sunscreen cream evaluation includes physicochemical testing (organoleptic, homogeneity, emulsion type, spreadability, viscosity, and pH) and sunscreen effectiveness (SPF, % erythema transmission, and % pigmentation transmission). The value of physicochemical testing are 5,96 cm - 6,3 cm of  spreadability testing; 83,33 dPa.s – 108,33 dPa.s of viscosity testing; 4,06 – 4,67 of pH testing. The value of sunscreen effectiveness are 9,79 – 13,35 of SPF testing; 4,55x10-06 - 0,15x10-06% of % erythema transmission; 5,77 – 7,16 % of % pigmentation transmission. The optimum formula was obtained by combining glycolic acid 2% and citric acid 0% with a desirability value of 0,649.

Potential of Seaweed in the Inhibition of Fungi Growth Aspergillus flavus. This use of synthetic chemicals as a controller of fungal growth in foodstuffs can have adverse effects on health, so it needs natural control ingredients that do not have an impact on human health. Various types of fungi such as Aspergillus flavus attack a lot of food items after harvest, these fungi can produce aflatoxin which is very toxic to consumers. Aflatoxin cannot be neutralized through cooking so efforts to avoid fungal contamination need to be done. One of the natural fungi controllers is by utilizing natural resources, including seaweed.  Development of seaweed as an antifungal is an alternative that needs to be realized.  For this reason, it is necessary to examine the potential inhibitory of seaweed A. flavus development. This study examined six types of seaweed like Gracilaria verrucosa, Euchema spinosum, Ulva lactuca, Ulva reticulata, Euchema edule, and Padina sp.  The results showed that Padina sp. seaweed has a very strong potential  inhibitory compared to other types of seaweed.

Average Maximum Temperature

An attempt is made to investigate the trend and variability for annual and seasonal (Three crop seasons) average maximum temperature (AMXT) for six divisional stations of Bangladesh: Dhaka, Rajshahi, Khulna, Barisal, Sylhet and Chittagong. The monthly AMXT (2009-2012) are forecasted applying univariate Box-Jenkin’s ARIMA (autoregressive integrated moving average) modeling techniques. The growth rates of annual AMXT are found positive in all the stations except Rajshahi (negative) while the rates of their coefficient of variations (CVs) are negative in all the stations except Khulna (negative). The rates of AMXT are positive during Kharif season but negative in Prekharif and Rabi seasons for Rajshahi and Khulna, positive during Kharif and Rabi season but negative in Prekharif season for Dhaka and Barisal and positive in all the three seasons for Sylhet and Chittagong. The findings support that the climate of this country is channging in terms of maximum temperature and this may have adverse effects on its agriculture.DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14803 J.
