“…Since growth is so intimately connected to the nutrients, it is very important to be aware of the nutrient concentrations when comparing the growth data. Stimulation of algal growth by pulp mill effluents has been observed in the field outside pulp mill industries and in the laboratory by a number of authors (e.g., [32,33]). Others, however, have observed the inhibition of algal growth (e.g., [30]).…”

Over the last decade, the use of ethylenediaminetetraacetic acid (EDTA) has increased by a factor of three within the Swedish pulp industry. The effects of pulp mill wastewater in combination with EDTA on metal mobility and the consequences for ecologically relevant organisms have been studied. Ethylenediaminetetraacetic acid was added to pulp mill effluent water in the laboratory and compared to wastewater without EDTA. Degradation of the water was followed over a experimental period up to eight weeks and samples were taken five times for chemical analysis and at the beginning and the end for biological tests. Half a year later, the experiment was repeated. The results from both experiments showed that EDTA markedly increased the solubility of zinc, cadmium, lead, iron, nickel, and copper, whereas the solubility of vanadium, molybdenum, thallium, arsenic, and chromium was not changed by the presence of EDTA. No measurable degradation of EDTA occurred even after 5.5 months. The toxicity of the pulp mill effluent water was low, and only a slight toxic effect was observed on the reproduction of Ceramium strictum. The most pronounced effect was a stimulation in the growth of three algal species in 5 to 20% (v/v) total effluent wastewater with and without EDTA. The presence of EDTA in the dissolved fraction of the pulp mill effluent water increased the growth stimulation in 20 to 40% (v/v), possibly because of the increased availability of essential metals like iron, zinc, and copper. The capacity of the pulp mill wastewater to support algal growth was nearly as good as a rich nutrient medium for algae. The combination of poorly degradable EDTA and the increasing availability of metals might further enhance eutrophication in the recipient areas of pulp mills.

A miniaturized and low-cost algal growth-inhibition assay, with Pseudokirchneriella subcapitata, based on the standard ISO 8692 and using 96-well microplates, was tested and optimized in this work, to be used as a useful tool for pollutant phytotoxicity screening. For validation, the performance of the microplate algal growth-inhibition assay was first compared with the standard flask assay for the toxicity testing of five reference toxicants (copper(II) sulfate, zinc sulfate, potassium permanganate, potassium dichromate and 3,5-Dichlorophenol) and six wastewater samples. Statistical evaluation of EC(50) results from both methods demonstrated a good agreement between microplate and flask assays either in testing chemicals (r (2) = 0.975, p < 0.0017) or environmental samples toxicity (r (2) = 0.984, p < 0.0001). In addition, the performance of this algal microplate bioassay was also evaluated in comparison with Lemna test, ISO 20079, for phytotoxicity assessment of 27 wastewater samples from industries and treatment plants. The results showed that the algal test was more sensitive for most of the samples, but a significant agreement between both tests was observed (r (2) = 0.644, p < 0.0001). In conclusion, this miniaturized test can be a good tool to include in a battery of tests for phytotoxicity screening of a wide range of chemicals and environmental samples, with the advantage of requiring low sample volumes for the test, allowing large numbers of samples to be tested, and generating low volumes of waste.

“…However, in many cases, the plant test species were more sensitive than animal species to effluents. Single species of algae have been used to determine the eco‐toxic effects of wastewaters from municipalities, textile, paper mill, mining, oil refinery and herbicide manufacturing plants . In this present work, the eco‐toxicity of degraded drug solutions was evaluated by green algae Chlorella pyrenoidos , which is found to be very sensitive to sulfamethoxazole and its degraded products.…”

BACKGROUND Sulfamethoxazole is found in surface and ground waters because it is usually not metabolized and simply passes through the human body after ingestion. This drug is difficult to degrade by conventional treatments and may cause environmental concerns. RESULTS A rapid and efficient enzymatic degradation of sulfamethoxazole by a heme peroxidase, chloroperoxidase (CPO), was investigated in this work. The degradation efficiency of sulfamethoxazole reached 98.64% within 20 min at room temperature, atmospheric pressure and environment‐friendly reaction conditions with an enzyme concentration of approximately 10−9 mol L−1. High performance liquid chromatography–mass spectrometry analysis was employed to identify the intermediates and final products. Moreover, chemical oxygen demand (COD) measurements showed that pre‐treatment by CPO‐H2O2 oxidative degradation followed by existing bioremediation technologies can effectively improve the efficiency and thoroughness of decontaminating this drug from wastewater. The degradation efficiency was enhanced from 76.5% to 84.47%, and the COD removal increased from 29.72% to 51.32%. The eco‐toxicity test using a green algae, Chlorella pyrenoidos, showed that the degraded products had lower toxicity than the parent drug. CONCLUSION CPO catalyzed oxidative degradation is a promising alternative for treatment of wastewater containing sulfonamide drugs. This enzymatic method is also suitable for treatment of other sulfonamide antibiotics. © 2016 Society of Chemical Industry
