Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Wastewater from the pharmaceutical industry is a significant source of contamination in the aquatic environment. Due to the absence of appropriate legislation, or challenges in the enforcement of existing legislation in many developing countries, many pharmaceutical companies employ improper disposal strategies for liquid and solid waste. As such, wastewater is usually released into the environment with little or no pre-treatment. The impact on the environment could be deleterious. This work, thus, evaluated the occurrence of pharmaceutical residues in soil and effluents from five pharmaceutical industries in Kumasi, Ghana and assessed the ecotoxicological risk posed by the presence of these pharmaceuticals to some organisms in the aquatic environment. Target pharmaceutical compounds (paracetamol, diclofenac, caffeine, amoxicillin, ciprofloxacin, and metronidazole) were quantified using an HPLC–PDA method. The concentrations of the pharmaceuticals were high, ranging from 1.17 to 350.55 mg/L in the water samples and 0.04–28.58 mg/kg in sediment samples. Diclofenac (350.55 mg/L and 28.58 mg/kg) and caffeine (27.69 mg/L and 36.36 mg/kg) showed the highest concentrations among the six-targeted compounds in water and soil samples, respectively. Paracetamol was the most ubiquitous analyte in both wastewater and sediment samples; its highest concentrations were 16.65 mg/L and 15.00 mg/kg respectively. Risk quotients obtained from the risk assessment were mostly > 1. Diclofenac posed the most significant risk to fish, daphnia, and algae (658.93, 15,934.10 and 24,175.86, respectively), while ciprofloxacin posed a moderate risk to fish and daphnia (0.27 and 0.57 respectively) in wastewater samples. For soil samples, diclofenac posed the greatest risks to algae (1968.28), whereas paracetamol posed the greatest risk to daphnia (1630.430). This is the first comprehensive study on the occurrence and ecological risk assessment of pharmaceuticals in industrial effluents of pharmaceutical manufacturing companies in Ghana. Routine monitoring of the effluents of pharmaceutical manufacturing facilities is necessary to reduce the influx of pharmaceutical compounds in various environmental matrices.
