ABSTRACT

The consumption of commercial bottled water worldwide has increased surprisingly. To ensure that its consumption has no harmful effects on human health, research must be carried out with living organisms. The growth of Nicotiana tabacum plants was analyzed after being irrigated with tap and commercial bottled water. Plants irrigated with commercial bottled water had leaves with chlorosis, smaller number of leaves with a shorter length of stem and leaf, compared to plants irrigated with tap water, and root, stem and leaf showed an increase of reactive oxygen species production with a significant decrease of chlorophylls. Chemical analysis of commercial bottled water showed a low ion concentration, and an acidic pH value (5.5) which is below the minimum of Mexican NOM-127-SSA1-2000 pH value standard (6.5–8.5). The growth, chlorophyll concentration and antioxidant capacity of plants irrigated with bottled water are negatively affected compared to those irrigated with tap water.

摘要

全球商业瓶装水的消费量惊人地增加了。为了确保其食用对人体健康没有有害影响，必须对活生物体进行研究。烟草的生长  用自来水和商业瓶装水灌溉后对植物进行分析。与用自来水灌溉的植物相比，用商品瓶装水灌溉的植物的叶子有褪绿病，叶片数量少，茎和叶的长度短，并且根，茎和叶的活性氧产生量增加，并且显着减少叶绿素。商业瓶装水的化学分析显示，其离子浓度低，且酸性pH值（5.5）低于墨西哥NOM-127-SSA1-2000 pH值标准的最小值（6.5-8.5）。与自来水灌溉相比，瓶装水灌溉植物的生长，叶绿素浓度和抗氧化能力受到负面影响。
