O princípio da justa indemnização à luz dos arts. 69o da Constituição da República de Cabo Verde e 62o da Constituição da República Portuguesa

O direito de propriedade privada consagrado em termos similares no artigo 69o da Constituição da República de Cabo Verde (CRCV) e no artigo 62o da Constituição da República Portuguesa (CRP) constitui não só um comendo ao legislador ordinário impondo-lhe a não irradicabilidade do instituto mas também um direito fundamental de natureza análoga à dos direitos, liberdades e garantias constantes do Título II da Parte II da CRCV e do Título II da Parte I da CRP. Daqui decorre, além do mais, que o direito à justa indemnização por ablação do direito de propriedade se constitui como um verdadeiro direito subjectivável na esfera jurídica do particular expropriado. Resulta ainda que o conceito de expropriação vertido nos dois textos constitucionais é diferente e mais amplo que aquele correntemente usado no direito civil e especialmente no direito administrativo.

Exposure of highway maintenance workers to fine particulate matter and noise

In this study, we assessed the mixed exposure of highway maintenance workers to airborne particles, noise, and gaseous co-pollutants. The aim was to provide a better understanding of the workers' exposure to facilitate the evaluation of short-term effects on cardiovascular health endpoints. To quantify the workers' exposure, we monitored 18 subjects during 50 non-consecutive work shifts. Exposure assessment was based on personal and work site measurements and included fine particulate matter (PM2.5), particle number concentration (PNC), noise (Leq), and the gaseous co-pollutants: carbon monoxide, nitrogen dioxide, and ozone. Mean work shift PM2.5 concentrations (gravimetric measurements) ranged from 20.3 to 321 μg m(-3) (mean 62 μg m(-3)) and PNC were between 1.6×10(4) and 4.1×10(5) particles cm(-3) (8.9×10(4) particles cm(-3)). Noise levels were generally high with Leq over work shifts from 73.3 to 96.0 dB(A); the averaged Leq over all work shifts was 87.2 dB(A). The highest exposure to fine and ultrafine particles was measured during grass mowing and lumbering when motorized brush cutters and chain saws were used. Highest noise levels, caused by pneumatic hammers, were measured during paving and guardrail repair. We found moderate Spearman correlations between PNC and PM2.5 (r = 0.56); PNC, PM2.5, and CO (r = 0.60 and r = 0.50) as well as PNC and noise (r = 0.50). Variability and correlation of parameters were influenced by work activities that included equipment causing combined air pollutant and noise emissions (e.g. brush cutters and chain saws). We conclude that highway maintenance workers are frequently exposed to elevated airborne particle and noise levels compared with the average population. This elevated exposure is a consequence of the permanent proximity to highway traffic with additional peak exposures caused by emissions of the work-related equipment.
