概括

农业食品废弃物回收工厂,就像alperujo干燥设施一样,对周围空气质量的影响很小. 然而,挥发性有机化合物 (VOC) 和微生物负荷需要进一步的环境评估.

科学领域:

环境科学环境科学
工业生态学工业生态学
空气质量监测空气质量监测

背景情况:

新兴行业正在利用农业食品废物,例如橄油生产中的alperujo.
这些废物处理过程可能会导致新的排放类型,特别是随着规模的增加.
评估这些新型产业对环境的影响对于可持续发展至关重要.

研究的目的:

为了评估一个alperujo干燥工厂对空气质量的影响,作为类似地中海工业的代理.

评估与这些工业排放相关的潜在健康风险和环境影响.

主要方法:

在Alperujo的干燥厂进行了为期六个月的实地活动.
监测的空气质量参数包括标准污染物 (NOx,O3,CO,SO2,PM10),金属和微生物负荷.
挥发性有机化合物 (VOC) 的表征是使用气体染色学和质谱学进行的.

主要成果:

该工厂对环境NOx水平 (3.0-12.5μg/m3) 的贡献很小,对O3,CO,SO2或PM10没有显著影响.
金属度很低,表明安全的健康风险条件.
细菌数量表现出受天气和PM2.5影响的季节性变化,在寒冷和温暖的季节之间有不同的主导属 (Cutibacterium, Bacillus).
乙酸,非酸和酸是最丰富的VOC,其中化物,乙酸和被确定为主要的气味贡献者.

结论:

阿尔佩鲁霍干燥厂对周围空气质量的影响很小.
具体参数,包括VOC和微生物负载,证明了需要进一步评估的环境影响.
建议进行长期监测和风险评估,以预见和预防潜在的环境影响.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Deleterious Substances in Aggregate

Deleterious Substances in Aggregate

Deleterious substances in aggregates can be detrimental to the quality and durability of concrete. These substances include organic impurities like loam, which interfere with cement hydration and are usually present in the sand. These prevent a good bond between aggregate and cement paste. Organic impurities can be detected using the colorimetric test, where the darkness of a solution after agitation indicates the level of organic content.
Another type of impurity is clay and fine material that...
