“…The Br:I ratio reached 2.66 in LAR. This ratio should be kept low to prevent goitrogenic effects derived from excess bromine [ 47 ]. However, it is known that Br is also an essential nutrient due to its requirements for collagen IV formation [ 48 ].…”

Laminaria digitata is a novel feedstuff that can be used in pig diets to replace conventional feedstuffs. However, its resilient cell wall can prevent the monogastric digestive system from accessing intracellular nutrients. Carbohydrate-active enzyme (CAZyme) supplementation is a putative solution for this problem, degrading the cell wall during digestion. The objective of this work was to evaluate the effect of 10% L. digitata feed inclusion and CAZyme supplementation on the meat quality and nutritional value of weaned piglets. Forty weaned piglets were randomly allocated to four experimental groups (n = 10): control, LA (10% L. digitata, replacing the control diet), LAR (LA + CAZyme (0.005% Rovabio® Excel AP)) and LAL (LA + CAZyme (0.01% alginate lyase)) and the trial lasted for two weeks. The diets had no effect on any zootechnical parameters measured (p > 0.05) and meat quality traits, except for the pH measured 24 h post-mortem, which was higher in LAL compared to LA (p = 0.016). Piglets fed with seaweed had a significantly lower n-6/n-3 PUFA ratio compared to control, to which the higher accumulation of C20:5n-3 (p = 0.001) and C18:4n-3 (p < 0.0001) contributed. In addition, meat of seaweed-fed piglets was enriched with bromine (Br, p < 0.001) and iodine (I, p < 0.001) and depicted a higher oxidative stability. This study demonstrates that the nutritional value of piglets’ meat could be improved by the dietary incorporation of L. digitata, regardless of CAZyme supplementation, without negatively affecting growth performance in the post-weaning stage.

“…The relationship between the calculated amount of seafood consumed per day and the concentration of the elements in breast milk was examined; correlations were found with Hg (0.531), Br (0.463), Se (0.409), and As (0.375). These four elements are elements typical of those contained in seafood [ 28 ].…”

For infants in the first months of life, breast milk is a complete source of nutrition; however, it can also contain elements that are harmful to the infant. It is therefore critical for infant health to characterize breast milk. The aim of this study was to determine the intra- and inter-day variation of elements in breast milk, for which there is currently limited information, as a pilot study for a larger study. Firstly, we developed a simple and robust analytical method for the determination of multiple elements in breast milk. It was accurate (accuracy ranged from 98% to 107%) for measurement of 26 elements in breast milk by quadrupole inductively coupled plasma-mass spectrometry. Intra- and inter-day variation of elements, protein, and fat in breast milk was determined by analyzing breast milk collected from 11 women at 12 sampling points over three days and calculating intraclass correlation coefficients. Intraclass correlation coefficients showed that while some elements were consistent across time points (e.g., Sr, Ca, and Cu), others showed very high variability (e.g., As, Cd, and Ni). Correlation analyses between elements in breast milk showed strong relationships between those including Fe and Mo, Ca and Sr, and Cd and Fe.

“…The World Health Organization (WHO) reports that about 1.6 billion individuals are at risk of iodine deficiency diseases worldwide (WHO, 2004).The main iodine supply occurs via nutrition and seafood is the most important natural source containing a relatively large amount of iodine (Eckhoff and Maage, 1997). Many researches on the iodine content of various fish species from different countries have shown that the accumulation of iodine in fish from different aquatic resources differs from species to species and often depends on the type of the species, environmental conditions, or can vary seasonally (Ansari et al, 2010 andSobolev et al, 2020).…”

The purpose of the current study was to determine certain mineral components in edible tissue in different species of fish from Greater Zab River, Erbil Governorate- Kurdistan Region-Iraq. A total of 180 fish namely Capoeta trutta, Chondrostoma regium and Leuciscus cephalus were collected from Gali Balinda, Bn Khiveta, Galiesule, Pirsal and Bekhme between July and November 2019. After removal of eviscerated, deboned, head and fins, fish were washed with purified water and muscle samples were collected above the lateral line between the dorsal fin and the caudal fin, then dried for important and non-essential metals examination at 750 C for 48 h. Results showed that levels of K, Na, P, Ca, Cd and Hg in the edible tissue of Chondrostoma regium fish were significantly higher than in the Capoeta trutta and Luciobarbus esocinus fish, whereas the edible tissue in Capoeta trutta exhibited the highest mean values for lead, barium and arsenic. In all species, the highest concentrations of K, Na, and Mg were recorded in Gali Balinda, whereas the highest concentration of P and Ca were recorded in Pirsal during studied period. According to the results, the government should have environmental policies to improve, keep and enrich the water quality assessment in Greater Zab River
