“…Port activity, including loading/unloading services, supplies, fuel, personnel transfer and repairs, can contribute to the presence of polluted dust in urban areas near ports. Dust in port areas may contain a variety of contaminants, such as Arsenic, Cadmium, Copper, Molybdenum, Lead, Zinc, organic matter, trace metals and polycyclic aromatic hydrocarbons (PAHs) [54].…”

In the present work, a study has been carried out on the contamination of heavy metals in urban dust deposited on the roads of the city of Cartagena (Spain) in order to know the content of metals such as Ni, Zn, Pb, Cd, Cr and Cu. Likewise, the possible relationship between the concentration of heavy metals and the color of the sample, level of magnetism and traffic density was studied. Contamination was evaluated using several indices such as contamination factor (CF), enrichment factor (EF), geo-accumulation index (Igeo), pollutant load index (PLI) and ecological risk index (RI). A total of 88 samples were taken in the urban area of Cartagena, and the metals were determined by acid digestion and measured by inductively coupled plasma mass spectrometry. The concentration of heavy metals in urban dust from Cartagena was Zn (672 mg kg−1) > Cu (248.9 mg kg−1) > Pb (227 mg kg−1) > Cr (82.7 mg kg−1) > Ni (47.7 mg kg−1) > Cd (4.1 mg kg−1). Contamination levels were high in Pb, Zn, Cd and Cu, according to environmental indices. A correlation was found between magnetism and metal concentration, which was repeated for all metals except Cd. Dark-colored samples contained higher metal concentrations than light-colored samples. Meanwhile, streets with medium and low traffic intensity were found to have higher concentrations of heavy metals. This study’s objective was to identify pollution hotspots caused by heavy metals in dust in the urban ecosystem of Cartagena city.

“…This area is also next to the military arsenal and the port and, therefore, is influenced by the presence of ships. The hotspot is in the vicinity of the port, where port activities generate a variety of pollutants [54].…”

“…Para determinar la concentración de espermatozoides adecuada para obtener porcentajes de fecundación superiores a 85%, se evaluaron concentraciones stock entre 7 x 10 4 y 100 x 10 6 espermatozoides. mL -1 utilizando 2000 ovocitos.mL -1 (Salas- Garza et al, 2005;Aguirre-Martínez et al, 2009). Las concentraciones de los gametos se prepararon adicionando el volumen calculado de gametos.mL -1 al volumen de AMF + UV; para el caso del esperma en tubos Falcon de 10 mL y para los ovocitos en un vaso de precipitado de 200 mL.…”

In Colombia, oil industry is interested in developing offshore hydrocarbon exploration, activity that causes spills of harmful substances in marine areas. It is essential to understand the effects that those substances may cause in native organisms in the inflence zones. This manuscript proposes an assay with an autochthonous organism from the Colombian Caribbean, that may be used as a bioindicator of contamination. The acute toxicity (CE50) of a flid used in offshore exploration was assessed on basis on the fecundity of the sea urchin Lytechinus variegatus, using as a standard toxic pentahydrated cooper sulfate. The protocol for obtaining the gametes and fecundation was previously standardized with the reference toxic which is used to guarantee and validate its results in terms of effective concentration (CE50). The fecundation percentage should be greater than 85% in order to validate the assay in the control treatment, that was carried out by fecundating 2000 oocytes with 50 x 106 sperms. In each replicate 200 oocytes (10%) were counted in order to determine the percentage of fecundation. The obtained CE50 value of pentahydrate copper sulphate was 20.45 ± 1.90 mg.L-1 and 3649 mg.L-1 ± 400 mg.L-1 corresponding to the suspended particulate phase of mud, which was prepared from a mud-water relationship of 1:9 (v/v). The results show a high sensitivity degree of the L. variegatus gametes to the action of the drilling mud of offshore hydrocarbon exploration, which shows the sensitivity of the test organism to these substances and its potential use as bioindicator of pollution.

In order to evaluate the health of Plicopurpura pansa, a species considered vulnerable, a population of this gastropod living in proximity to the port of greatest cargo movement in Mexico was monitored seasonally during 1 year. Morphometric characteristics and sexual proportion were recorded. A macroscopic analysis was carried out to detect malformations and imposex; a histological analysis was performed to evaluate disseminated and gonadal neoplasias; the presence/absence in soft tissues of butyltin species (BTs) as possible contamination agents was also estimated. A total of 508 P. pansa specimens were collected. The largest specimens were obtained in winter. The coefficients of determination inside the port were low (R = 0.453). In general, there was a greater proportion of females than males throughout the year. Distinctive foot malformations (tumors) were recorded, but without signs of imposex. The histological examination confirmed the presence of disseminated neoplasias in the foot and gonads of P. pansa in the Port of Manzanillo. The comparative analysis of the morphological and histological features of the studied gastropod population allowed us to recognize impact patterns in relation to proximity to the port. There were high concentrations of monobutyltin (MBT) and greater abundance of tumors in heavier specimens; this was associated with port proximity zones. P. pansa could therefore serve as a sensitive bioindicator of environmental health in marine systems.
