“…Also, norethindrone, levonorgestrel, estriol, pregnenolone, diethylstilbestrol, and androstenedione were detected in none of the samples. On the other hand, estrone was the natural estrogen most frequently detected in all other types of water (well, pond, swimming pool, and river), but especially in Spanish and Moroccan river water (concentrations of 13 and 83 ng L −1 , respectively), which are similar to those of coated South Florida surface water, where it was encountered at levels up to 79.5 ng L −1 by Ng et al (2021). One other hormone found in many samples was dihydrotestosterone (28-64 ng L −1 ).…”

Over recent decades, steroidal estrogens have become an emerging and very serious issue as they pose a serious threat to living organisms, soil, plants, and water resources in general. Estrogens have therefore been the subject of considerable scientific attention in order to develop new methodologies for its determination, being able of detecting them at very low concentrations. Those procedures minimize or eliminate the consumption of organic solvents and reagents that may be incompatible with the environment. In this respect, we developed a sensitive, selective method for the simultaneous determination of thirteen natural and synthetic hormones present at the nanogram-per-liter level in various types of water by using continuous solid-phase extraction in combination with gas chromatography and mass spectrometry (GC–MS). The target analytes were preferentially sorbed on an Oasis HLB sorbent column (80 mg) and eluted with acetone (600 µL) for derivatization with a mixture of 70 µL of N,O-bis(trimethylsilyl) trifluoroacetamide and trimethylchlorosilane and 35 µL of petroleum ether in a household microwave oven at 200 W for 4 min. Under optimum conditions, the ensuing method exhibited good linearity (r ≥ 0.998), good precision (RSD ≤ 7%), high recoveries (92–103%), and low detection limits (0.01–0.3 ng L−1). The method outperforms existing alternatives in robustness, sensitivity, throughput, flexibility—it allows both estrogens, progestogens, and androgens to be determined simultaneously—and compliance with the principles of Green Chemistry. It was successfully used to analyze various types of water samples (mineral, tap, well, pond, swimming pool, river, and waste) that were found to contain four estrogens (estrone, 17β-estradiol, 17α-ethinylestradiol, and hexestrol), two progestogens (testosterone, dihydrotestosterone), and one progestogen (progesterone) at concentrations ranging from 3.0 to 110 ng L−1.

One recent trend in Analytical Chemistry is to develop economical, fast green methods using minimal amounts of solvents to determine a variety of analytes spanning a wide range of physicochemical properties. In this work, we developed a sensitive, selective method for the simultaneous determination of thirteen natural and synthetic hormones present at the nanogram-per-liter level in various types of water by using continuous solid phase extraction in combination with gas chromatography and mass spectrometry (GC–MS). The target analytes were preferentially sorbed on an Oasis HLB sorbent column and eluted with acetone for derivatization with a mixture of N,O-bis(trimethylsilyl) trifluoroacetamide and trimethylchlorosilane in a household microwave oven at 200 W for 4 min. Under optimum conditions, the ensuing method exhibited good linearity (r ≥ 0.998), good precision (RSD ≤ 7%), high recoveries (92–103%) and low detection limits (0.01–0.3 ng L− 1). The method outperforms existing alternatives in robustness, sensitivity, throughput, flexibility —it allows both estrogens, progestogens and androgens to be determined simultaneously— and compliance with the principles of Green Chemistry. It was successfully used to analyze various types of water samples (mineral, tap, well, pond, swimming pool, river and waste) that were found to contain four estrogens (estrone, 17β-estradiol, 17α-ethinylestradiol and hexestrol), two progestogens (testosterone, dihydrotestosterone) and one progestogen (progesterone) at concentrations ranging from 3.0 to 110 ng L− 1.

“…Both PhaCs and PCPs could act as endocrine disruptors for marine organisms [55]. Most of the detected impacts or damages are related with alteration of reproductive capability, problems of growth and decrease of survival rates and these negative effects have been reported even at trace concentrations (ng L −1 ).…”

“…Other concern family of emerging compounds is hormones. The HQ of estrone, 17β-estradiol, estriol and 17-α-ethynylestradiol were evaluated in Biscayne Bay in Florida (USA), resulting in an unexpected high risk probably related with surface runoff and groundwater flow in coastal areas not served by municipal wastewater collection [55]. Despite estriol showed the highest environmental concentrations, the HQs calculated for estrone, 17-β-estradiol and 17-α-ethynylestradiol were higher, as much as 651 for 17-αethynylestradiol.…”

Emerging Contaminants in Seafront Zones. Environmental Impact and Analytical Approaches

Some chemical substances have the potential to enter the coastal and marine environment and cause adverse effects on ecosystems, biodiversity and human health. For a large majority of them, their fate and effects are poorly understood as well as their use still unregulated. Finding effective and sustainable strategies for the identification of these emerging and/or anthropogenic contaminants that might cause polluting effects in marine environments to mitigate their adverse effects, is of utmost importance and a great challenge for managers, regulators and researchers. In this review we will evaluate the impact of emerging contaminants (ECs) on marine coastal zones namely in their ecosystems and biodiversity, highlighting the potential risks of organic pollutants, pharmaceuticals and personal care products. Emerging microextraction techniques and high-resolution analytical platforms used in isolation, identification and quantification of ECs will be also reviewed.
