“…Molybdenum (Mo) was also detected in samples of all meliponaries (except in meliponary G -control), with the mean concentrations ranging from 0.0063 (SD = 0.0117) to 0.2818 (SD = 0.1756) mg/kg. Bonsucesso et al (2018) conducted a study in the same sampling site of our research and reported that Mo was also detected in samples of M. scutellaris geopropolis of all meliponaries. The tolerable limit for Mo in water is 0.700 mg/L established by resolution No.…”

“…In a study on soil samples and geopropolis (bee stingless propolis) of M. scutellaris, Bonsucesso et al (2018) found that most contents of the metals investigated in geopropolis had the soil as source. In addition, other external sources can contribute to the increase of metal concentration in geopropolis.…”

Melipona scutellaris (Apidae, Meliponini) is one of the main species of stingless bees used in beekeeping in the Northeast of Brazil. We examined the honey from M. scutellaris as an indicator to evaluate the levels of metals at sampling sites subject to a broad spectrum of environmental pollutants. The collections were carried out in the urban-industrial area of Salvador, Bahia and the metropolitan region. Samples (n= 58) were submitted to the nitroperchloric digestion procedure. We used the inductively coupled plasma optical emission spectrometry technique (ICP OES) to determine the concentration of metals (Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb and Zn) in the samples. The studied metals were detected among the samples, which presented tolerable levels according to current Brazilian legislation and recommendations from the World Health Organization (WHO), except for Cr, which presented mean values higher than the threshold for all sampling sites. The detection of the analyzed metals indicates that the honey of M. scutellaris is a useful tool to evaluate the presence of environmental contaminants; therefore, it can be considered a good indicator of environmental contamination for monitoring a particular region and preventing issues due to the release of metals into the environment.

“…Several techniques can be used to detect metals in hive products, such as Inductively Coupled Plasma Atomic Emission Spectrometry (ICP AES), Inductively Coupled Plasma Optical Emission Spectrometry (ICP OES) and Differential pulse anodic stripping voltammetry (DPASV) [13][14]. Determination by ICP OES is the most commonly used technique in studies of geopropolis, presenting satisfactory results [15][16][17]. The principal advantage of this technique is the possibility of selecting the optimum  (wavelength) for each element in any type of sample.…”

“…Geopropolis is a product of stingless beehives, which has aroused the interest of researchers because of its use in environmental quality monitoring, as well as for its chemical characterization [15,[19][20]. Geopropolis is a particular type of propolis, because it contains a mixture of resin and exudates from various plant sources, mixed with wax, silt, and soil particles, which gives it specific characteristics [21][22].…”

This study evaluates the efficiency of acid extraction and total digestion to determine the presence of metals in geopropolis produced by the stingless bee Melipona scutellaris. Geopropolis samples were collected at five meliponaries in the city and in the metropolitan region of Salvador, Bahia State, Brazil. The sample treatment methods comprised acid extraction and total digestion. The Inductively Coupled Plasma Optical Emission Spectrometry (ICP OES) technique was used to quantify Cd, Cu, Cr, Pb, and Zn. Geopropolis samples submitted to both digestion methods showed statistical differences. For both methods, Cr and Zn showed the highest concentrations, while those of Cd were the lowest. The Cr concentration for determination by total digestion was 37.53 mg/kg, while for acid extraction it was 32.90 mg/kg. For Zn, the concentration was 17.65 mg/kg and 8.85 mg/kg for total digestion and acid extraction, respectively. The total digestion method showed the highest concentrations of the metals evaluated; however, acid extraction (USEPA 3050b) is a more straightforward procedure for metal evaluation in geopropolis samples and presented values that support the use of geopropolis as a bioindicator. The acid extraction method USEPA 3050b, in combination with detection using ICP OES, showed efficiency in analyses carried out to determine metals in geopropolis.

Bacteria are associated with many infections that affect humans and present antibiotic resistance mechanisms, causing problems in health organisations and increased mortality rates. Therefore, it is necessary to find new antibacterial agents that can act in the treatment of these microorganisms. Geopropolis is a natural product made by stingless bees, formed by a mixture of plant resins, salivary secretions, wax and soil particles, presenting a diverse chemical composition. Thus, this study aimed to evaluate antibacterial activity, antibiotic modulation and the toxicity of geopropolis extract from the stingless bees, Melipona subnitida (Ducke, 1910) and Scaptotrigona depilis (Moure, 1942) against standard and multi‐resistant Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa bacteria. Geopropolis samples were collected in a meliponary located in Camaragibe, Pernambuco, Brazil. To determine the Minimum Inhibitory Concentration (MIC) and antibiotic modulation we performed broth microdilution tests. Mortality tests were used to verify extract toxicity in the model Drosophila melanogaster. The microbiological tests showed that the M. subnitida extracts had better inhibitory effects compared to S. depilis, presenting direct antibacterial activity against standard and multi‐resistant strains. The extracts potentialized antibiotic effects, suggesting possible synergy and did not present toxicity in the model used.
