Sustainable consumption: the effects of knowledge,cultural values,environmental advertising,and demographics

As a result of human lifestyles and unsustainable consumption patterns, the environment continues to deteriorate and thus inhibit sustainable development. In order to curb this situation and promote a sustainable economy, one of the solution is to reduce conventional products consumption and shift to green products. Over the past 20 years, marketing managers keenly seek to understand the green market; however, inadequate information on how to promote consumers’ green behavioral intentions is slowing the growth of green markets and becomes a barrier for firms when developing segments and communicating strategies for effective promotion of green products in countries like Malaysia where the trend is fairly new. Therefore, this study attempts to examine the impact of environmental knowledge, cultural values, and environmental advertising and determine the moderating effect of income level, education level, and gender on consumers’ green purchase intentions. A survey was administered, and a total of 405 valid questionnaires were obtained. Structural equation modeling technique was used to evaluate the causal model by using SmartPLS 2.0 software. The finding results suggest that cultural values and environmental advertising are the main influences in building green purchase intentions, while environmental knowledge is not significantly related. The results also indicate that education level and gender have a significant positive moderation effect while income did not. This suggests that green purchase intentions’ motivational factors are greater among highly educated individuals, with females in particular. The discussions and implications of these findings are further elaborated.     

Effect of cobalt-supplemented diets on bioaccumulation,digestive enzyme activities and growth of Cyprinus carpio

Experiments were conducted to determine the effects of excess dietary cobalt (Co) on bioaccumulation, digestive enzyme activities, and growth in freshwater Cyprinus carpio. Four isonitrogenous diets (average crude protein: 35%) were formulated to prepare a control diet (T₁) with no Co, and three Co-supplemented diets with 1 (T₂), 1.5 (T₃), or 2 (T₄)% Co. The results showed that C. carpio fed with T₃ diet showed maximal apparent protein digestibility, feed conversion, protein utilization, and growth. Protease and lipase activities were maximal in the fish group given T₃ diet. Accumulation of Co in different soft and hard tissues of fish did not correlate with levels of Co in the diet. The concentration of Co in the water increased with dietary level, being at a disturbing adverse effect level at 2% dietary Co. Evidence indicates that an additional supply of dietary Co up to a level of 1.5% is a viable option to augment growth of C. carpio, but at higher levels of Co it may be detrimental to fish health and the aquatic ecosystem.

Metal uptake capability of <Emphasis Type="Italic">Cyperus articulatus</Emphasis> L. and its role in mitigating heavy metals from contaminated wetlands

Wetland plants are biological filters that play an important role in maintaining aquatic ecosystem and can take up toxic metals from sediments and water. The present study investigated the seasonal variation in the accumulation potential of heavy metals by Cyperus articulatus in contaminated watercourses. Forty quadrats, distributed equally in 8 sites (six contaminated sites along Ismailia canal and two uncontaminated sites along the River Nile), were selected seasonally for sediment, water, and plant investigations. Autumn was the flourishing season of C. articulatus with the highest shoot density, length, and diameter as well as aboveground biomass, while summer showed the least growth performance. The photosynthetic pigments were markedly reduced under contamination stress. C. articulatus plants accumulated concentrations of most heavy metals, except Pb, in their roots higher than the shoots. The plant tissues accumulated the highest concentrations of Fe, Cd, Ni, and Zn during autumn, while Cu and Mn during spring, and Cr and Co during winter. It was found that Cd, Cu, Ni, Zn, Pb, and Co had seasonal bioaccumulation factor (BF) > 1 with the highest BF for Cd, Ni, and Zn during autumn, Co, Cu, and Pb in winter, spring, and summer, respectively. The translocation factor of most heavy metals, except Pb in spring, was <1 indicating potential phytostabilization of these metals. In conclusion, autumn is an ideal season for harvesting C. articulatus in order to monitor pollution in contaminated wetlands.
