Aiming at the imbalance of urban ecological carrying capacity, this paper proposes a method to estimate the ecological and cultural carrying capacity of British urban agglomeration. The difference method and standardization method are used for positive combination and dimensionless processing of the indicators to realize the data preprocessing of the indicators. Through questionnaire survey, consulting relevant scholars and experts, and referring to the specified values in relevant British policies, determine the ideal value of the index. The index weight is determined by the open-scoring method. According to the index weight, the ecological and cultural carrying capacity of British urban agglomeration is calculated by vector model method. Calculate the index weight according to the ideal value of the index and the ecological text. The strength of ecological culture carrying capacity is calculated by the actual value of carrying capacity. Taking London urban agglomeration as the experimental object, this paper calculates the ecological and cultural carrying capacity and analyzes the ecological and cultural carrying capacity of three subsystems. The results show that this method can effectively estimate the ecological and cultural carrying capacity of British urban agglomeration.

“…Likewise, environmental contamination by heavy metals also presents a major ecological factor and an associated health risk. Chromium [Cr] was chosen as the heavy metal to focus on in this study as it has been listed by the Environmental Protection Agency as one of the most common and noxious contaminants (Sharma et al, 2012;Vimercati et al, 2017) and has been used as a soluble reference chemical for toxicity testing in Artemia salina (Kos et al, 2016;Persoone et al, 1989). Cr primarily exist in two stable oxidation states: hexavalent Cr [Cr(VI)] and trivalent Cr [Cr(III)].…”

Combined effects of nano-TiO2 and hexavalent chromium towards marine crustacean Artemia salina

There has been a significant increased concern of the impact of the toxicity of multiple contaminants in the marine environment. Thus, this study was aimed at determining whether the interaction between nano-TiO 2 and Cr(VI) would modulate their toxic effects with the marine crustacean, Artemia salina. Nano-TiO 2 agglomerated in artificial sea water (ASW) and readily formed micron-sized particles that settled down in the medium. The addition of Cr(VI) to nano-TiO 2 aggravated their agglomeration through sorption of Cr(VI) onto nano-TiO 2 . This was reflected by a decrease in the residual concentration of Cr in the suspension. Acute toxicity tests performed using pristine nano-TiO 2 (0.25, 0.5, 1, 2, and 4 mg/L) and Cr(VI) (0.125, 0.25, 0.5, and 1 mg/L) displayed a concentration dependent rise in the mortality of Artemia salina. To examine the effects of mixtures of nano-TiO 2 and Cr(VI) on Artemia salina, two groups of experiments were designed. The former group studied the toxic effect of nano-TiO 2 (0.5, 1, 2, and 4 mg/L) with a fixed concentration (0.125 mg/L) of Cr(VI). While the latter group studied the toxicity of Cr(VI) (0.25, 0.5, and 1 mg/L) with a fixed concentration (0.25 mg/L) of nano-TiO 2 . The toxic effects of nano-TiO 2 was not significantly reduced at a fixed concentration of Cr(VI) but in contrast, a significant reduction in the Cr(VI) toxicity by fixed concentration of nano-TiO 2 was observed. Toxicity data was well supported by an independent action model that proved the mode of action between nano-TiO 2 and Cr(VI) to be antagonistic. Furthermore, ROS generation and measurement of antioxidant enzyme activities were also in line with toxicity results. From this study, the modification of Cr(VI) toxicity at fixed concentration of nano-TiO 2 could have a huge impact on the reduction in Cr(VI) toxicity across trophic levels.
